I got this Blc at Parkside.
A couple of days ago i noticed the base of the leaves was black and fell off.
pulled out of the medium and it smelled a bit mold-like.
i rinsed in peroxide cleaned etc.
some PB are not too firm.
is it a fungus?
was wondering if it is worth to try to rescue or it could spread disease and then would be just better to dispose.
my small catts are doing well. new roots etc. So i do nit understand why this got sick.
Maybe the plastic pot instead or clay that I use for most?
I bought also some Daconil spray fungicide but it is very dense so hard to apply inside from a close range.
Is neem oil a good fungicide?
Anywa is this rot due to fugus?
thanks

]]>I have these spots on a Prosthechea radiata (Encyclia radiata)
I just bought it, I saw the spots, but I don't want to give it back, it seems such a nice, fragrant lady..
So I would like to save it, if it's not that bad..
These spots are on a couple of leaves, there are fresh new ones, unaffected.
Is it fungus, is the bacterial brown spot?
What do I do, do I cut the affected areas, how do I get rid of this?
Thanks so much.

LE: Would it be this? I found it following the pest link..
There is quite a resemblance, but I am not 100% sure

New to the board and new to orchids, I bought a few a couple of weeks ago and have been doing a lot of readin, want to make sure that I can take care of these ones before I get more "advanced" plants.
Anyways one of the orchids has a dark spot on the leaf, not sure if this is from shipping or if it is fungus, I can't tell if the spot is growing but 2 small holes have developed above the spot (which are hard to see in the picture, but they we not there yesterday)
Do i remove the leaf?
Treat for bugs?
Treat for fungus?
Leave it alone?
Great forum by the way, I really enjoyed reading through the posts, I have learned a lot already.
]]>Secondly, I have a Phal. Ever Spring 'Pearl' which I rescued from the same nursery as the Mtssa mentioned above. Unlike the Mtssa, I've had phals for years. It was in horrible shape when I got it, sitting in sopping wet peat moss, with most of its roots rotted. Since I repotted it in bark, it's made a great come back-lots of new roots and even two spikes! It's in spike right now with a few big buds (I accidentally broke off a young spike 2 months ago when I was moving). The past 2 weeks or so I have been concerned about its health. Two leaves have turned yellow and fallen off and one is in the process of turning yellow. I have no idea as to what is causing this. It is not in the normal way a phal looses it's leaves--they are still pretty fleshy, but yellow.
What is wrong with my two plants?
Any help is greatly appreciated.
Thanks,

I'm just not sure what to think about them. These have never bloomed, which makes me sad but maybe next year if they survive.
Is there anything special I need to do for these or are they growing (and dying) naturally? They aren't as 'glossy green' as they were when I first got the plant, which concerns me about the lighting I have them in. I've had them in a couple different places, right now they are in front of a northeast window with a little morning sun/light. I also have a lamp lite on that table at night, as well.
Thanks for any help! :bowing I tend to let orchids take their course because I get rather nervous about how to care for them and whether or not I am doing the right thing, so any help would be appreciated.

]]>The confusing this is, where the stem of the leave separates from the rest of the plant....it looks like what I would think stems would look like if a tiny animal had chewed on them (wish I had a photo) to separate them. There is no discoloration, and the leaves do not appear to be wilting or under and other sign of stress.
I'm hoping someone else has had this problem, or knows what could be going on. thanks in advance. ]]>

This is a little rescue den I bought at Lowes about 6 mo. ago, and recently I've noticed the leaves on the older growths have developed yellow/green splotches. The 2 new growths appear fine. Green and healthy. The leaves on the entire plant are firm. No mushiness. Could someone please tell me if this is a fungal, bacterial....and goodness forbid, a virus problem?
Vicki
By the way, I promised a friend awhile back that I would never buy any more Lowes orchids because I have had so many problems with them.....so "Debs, I bought this orchid BEFORE I told you this". :blushing:
roots are growing nicely and it has been in s/h for over three months now untill just a week or two ago when suddenly one areial root developed a section of root that just suddenly shriveled up.THis is just a small section in the middle of the root and the growing tip looked good and the section before this spot still looks fine.
after three or four days growing tip drys out and the root dies then from this point to the tip.
What could be causing this?There are no bugs and It is not rotting and it is not wet and soggy.It simply looks as if something has caused it to dehydrate in this middle section.The velumin actually shrinks and then it dies from this point uot to the end.
I cut this part off a inch or so ahead of this point and it seems fine then It has happend twice now on two different roots. ]]>
Is this bacterial, fungal, or viral?
How else should I treat it?
Thanks for your help,

Within days, it was obvious that one had a fungal infection, so I repotted,disinfected, did all the things I'm supposed to do, very thoroughly. The roots weren't great, but still OK for a supermarket phal. In less than a week, however, significant balls of fungus were visible through the pot, (like 1"/ 3 cm across) and it has been like this for the past month maybe. I spray everyday with fungicide, and every time the problem seems sorted, another ball crops up somewhere else.
The other one just had bad root rot from the store, so I cared for it with the KLN and rested it on bark chips to get some more roots (it had 3 passable ones left). This one, however is now badly infested with fruit flies/ fungus gnats which it must have carried with it given the state of its root system. This makes me think that there may well be a fungal infection there too!
The thing is that both of these phals seem to be clinging to life- the second ones leaves have definitely improved, so I'm reluctant to bin just yet, but it is difficult keeping them isolated from my other chids in my small flat. At the risk of sounding an orchid snob, I also don't want to waste any more decent potting medium and expensive chemicals on 2 fairly worthless plants.
Should I just give up? Or should I wait until they decide to die? Or is there some sort of miracle cure I've yet to find? I can't quite bring myself to throw them in the bin!
Thanks!

suddenly during the night literaly I had one areial root developed a section about one inch long in the middle of the root just shrink and whither.IT isnt mushy it isnt discolored It is really not mushy feeling.The root on either side looks normal and healthly to me although all the roots did decide to stop growing this week and the tips have sealed themselves up.
I have new eyes in active growth and about one to two inches tall with new leaves emerging right now so the plant seems to be growing great.

As far as culture, they're in 65-70% humidity, low light, fan about 6 feet away, air around 65 degrees at night 70 degrees during the day. Sphagnum around the roots in a teak basket. Water every 3-4 days as the sphagnum dries
My Stanhopea grandiflora is starting to develop spots on the leaves...i'm really hoping they're not going to have to be sacrificed...
well my phal does not seem to be doing well:(. after repotting it a couple weeks back and removing bad roots, it only had 4 small good ones. after not having any medium for a week, i finally purchased bark,ch,and perlite mix. i didnt soak it, after a couple of days i realized this and when i took the orchid out and the roots green was squeeshy and the root was dried out and some of the stem. I purchased rooting hormone powder for the stem and a leaf that fell off. I also purchased orchid moss. It still doesnt seem like its ok...

I bought Miltassia Peggy Ruth in February. Grown-up, healthy one. Special orchid ground, watering once a week, T=21-23C.
No problems with the roots, neither with leafs. But I have a problem with its buds and absence of blooming.
First it gave two buds in June and both dried off. Second time in the mid of September it gave two arrows with two buds each and one of the buds already dried off. Others are still green and healthy but not blooming yet. You can see dried off bud on the foto.
Please advise what can I do to support blooming?

i've really gotten into angraecums recently. i have three Angraecum magdalenae seedlings from various places, two larger magdalenae plants, and a Lemforde 'white beauty.'
i JUST got the really big magdalenae and lemforde in the mail two days ago. i knew that this particular vendor wasn't the most modern and that the plants' condition wouldn't be the same caliber as say, Oak Hill Gardens. but larger Ang. magdalenae are (at least for me) really hard to find. As a side note- I paid $70 for the magdalenae. that's a record amount for me :(
when i got them in the mail, i placed them in a section away from my other plants. today i watered them for the first time. i sat them in a bucket of water, so the water would rise to the rim. after a few minutes ALL KINDS OF CRITTERS EMERGED! there were snails, slugs, centipedes, milipedes (yes, both), and some super tiny flea-like things that are offwhite and jump super fast.. still don't know what those are.
i'm paniced!
i'm not asking for a refund or complaining to the vendor, they're elderly and i'm just glad i was able to find a plant this size.
i don't want to use some super insecticide because i don't want to injure the plant. i also don't want to kill any good fungus/bacteria. there's no way i can repot it because angraecums are so sensitive about repotting. it's almost winter and i think that would do more harm then good.
i don't regret buying them... despite the bugs... the cracked pot... the slimey moss/algae/dirt all over it.... :dumb:
if anyone has experience with Angraecums.. specificially magdalenae.. i could definitely use some advice.. if this were just one particular pest on a less rare (and expensive) plant i would be a little less calculated in my approach. but i want to really be sure before i make any actions.
:violin:
Background: My miltoniopsis recently finished flowering, and maybe 2 days after cutting down the stem I found the white fluff over some of the aerial roots and between 2 pseudobulbs (where there are also some roots). At first I thought it was maybe some sort of mould, but was puzzled, as they have good ventilation etc. I treated with listerine, and nothing happened.
I repotted, seeing as it is repotting time anyway, and didn't want to leave an orchid in a potentially infected medium. I discovered that ALL of the roots in the medium were perfectly healthy. No need to deal with a single one.
So, could this white fluff be mealies? ( sorry no camera cable for picture uploading) I've also sprayed my 'chid with pesticide (again no visible improvement). Would anyone seriously recommend the paintbrush and meths technique on roots??!!!
On the upside, other than that, the orchid seems fine, happy, and even seems to be putting out some new growth, so go figure!
Any thoughts please? Can you even get mealies on roots??

Did I do anything wrong? Should I pack it tight or loose? Should I wait until it crispy to water it?

Has anyone used this on orchids? Specifically I want to treat Guignardia Leaf Spot caused by Guignardia species on vandaceous orchids.
Most of us in the deep south, especially along the Gulf and Florida coasts, are familiar with this apparently airborne fungus that has our foliage resembling the texture and color of an emery board after awhile...every time a hurricane blows through, this fungus seems to come with it.
So, my questions: did you use a buffer/spreader to adjust pH? I had planned to spray the affected foliage only, and also saturate the roots, since I believe this is at least slightly systemic.
Any tips very gratefully solicited. Or any thoughts.
Regards - Nancy, queen of the unsightly fungus
I bought an orchid a year ago, and in that time the original blooms lasted over two months, the stalk dried up completely, and it grew another two leaves. It never has bloomed again.
This past July, the bottom leaf turned yellow and dropped. Concerned I did some research and concluded it was just an old leaf falling of. But then I went away, had someone take care of my plants, and I'm pretty sure she over watered everything, since my african violet freaked out and dropped almost all of its mature leaves. Anyway, I returned and thought the orchid had survived. That was in mid-August.
Three days ago, I was lightly dusting off the leaves, and one side of it literally lifted from the pot! I also noticed the now most bottom leaf was getting a bumpy texture, and was wilting. So again I did some research and repotted it using a fir bark / charcoal mixture, making sure to soak it over night. There had been one air root, and only one root left within the compost. I put both in the new compost, and this time, chose to use a 4" terracotta pot. By the next morning, the bumpy leaf started to turn yellow.
Today, however, I was just looking at it, sending it loving energy, and noticed the one root that had been in the compost before, is now not as green - more brown, and has a layer of black where it's exposed to the air. I didn't sterilize the roots when I repotted it; I didn't know to. For a temporary measure, I took some shavings of cinnamon and touched the root and the underside of the plant with it.
So now the plant has four very healthy firm leaves (one of which is still growing), a wilted half yellow leaf, and one healthy once was air root in the compost, and another root browning near the base (not the end) with a slight layer of black and a few shavings of cinnamon.
I hope this is enough information to go on.
Please help.?. ]]>
so this morning, i was examining my phals to see if they needed watering, and i noticed that there was white stuff all over my phals roots! i could see it through the clear container. so i pullled the roots out to examine closely. the substrate seems to be primarily bark with a bit of moss.
i just bought this phal last week. i only watered it once. i don't believe this white junk was there when i purchased it... although it is hard to believe. i guess its possible it was.
what do you think this is? what should i do? when i repot should i get new substrate?
I am now noticing them on my Suksamran Sunlight :(( - what can I do to remove the bugs and save this spike before it is too late?
Thanks,

the first two images are the same plant... there is a straw colored spot that has made the leaf almost see-through... as you can see its the only spot on the plant. the rest of the plant seems happy since its strongly putting out a new sprout of leaves
the third and fourth are of a vanda that i bought knowing it wasnt doing so well... the bottom two leaves are yellow and the roots arent turning as green as my other vandas during watering. the plant is desperately trying to bloom though! (also not looking too good)
lastly is a new vanda i came across, the roots looked fine when i bought it however once i watered it tons of white dots appeared (is this normal for some types??)... it seems to be healthy otherwise and is in strong bloom, looking much healthier than the previous plant mentioned...
sorry if the questions seem silly!
I use charcoal as the medium.

so I just got a few orchids for my dorm room from Lowes less than a week ago, and after doing some research, I realized that the brown spots on the leaves of one of the orchids may actually be a fungus.
The brown spots are mainly on only one leaf of one orchid, and are actually indented into the leaf, so the brown spot is actually depressed.
2 of the pictures are of the front part of the leaf, and 1 is a shot of the backside.
Does Lowes have a history of selling bad orchids? Or is this just due to the orchids mistreatment?
I am new to the forum, and hate to start off with a question instead of a formal introduction but i have a serious issue that needs to be fixed asap. I have various jewel orchids growing in a large vivarium along with tons of other plants. I recently ordered a dossinodes indras web and a ludisia discolor "black" from the states, and within 1 week both plants died mysteriously. Both had similar symptoms. They started losing their shape, and their stems turned to mush. I removed them, but now my normal ludisa discolor have started to wilt. I removed one and under observation with a microscope noticed tons of white mealy bugs crawling everywhere. I shook it and had around 10 little bugs that looked grey in color and elliptically shaped.
Im very worried about this as i have some very rare and expensive plants in there, along with dart frogs. I cant spray pesticides as its a vivarium, so i need a solution fast.
Thanks! ]]>
Earlier this morn. I noticed a few very, very tiny black ants on one of my catts.....especially on a new growth. I tried to take a pic of them on the plant, but my camera wouldn't cooperate.....so I was only able to take some not so good ones on a tray sitting beside the plant.
Can you tell me if they will do harm, or should I not be concerned that they're crawling around on it?

I got it this febuary and one new growth is fully developed and ive got another one coming. But there is one slight problem. I can see that the other older growths had it too. There is also brown dots all over the leaves it dosent seem to affect the plant but i dont like the look of it. Again what is it and how do i fix it?
3.I have 3 Miltonia HYBRIDS that i am really on the verge of losing. Before i left they seemed happy with green growth and the older leaves yellowing. But now apperently all the leaves started yellowing and falling off. The new growth is soft and breakcable, almost transparent in some places. Bearly has any good leaves exeppt for one which seems to be doing much better than the other two. I think that one is still good.

One plant has sunken dry white patches and browning tips on some of the newer leaves.
The other plant has no white patches...only brown circular spots and tips with lack of pigmentation along their borders. One of it's newer leaves exhibits an irregular brown pattern and yellow die back from the tip. There is one older leaf that appears to be yellowing as a result of old growth dieback.
After carefully examining the upper and lower leaf surfaces of both plants I cannot find any signs of insects other than ants and what appears to be ant poop. Wasps sometimes pay a visit. Tree frogs and lizards are in abundance.
These plants are suspended growing vertically with a Schomburkia growing between them. The Schom looks fine. They've been flourishing and have numerous swollen sheaths. The uppermost plant had a large decorative (unknown metal) and glass bead butterfly attached to the mount. Last week I suspected the rusting metal may have been causing the symptoms so I removed it from the mount.
I'm beginning to get concerned. I have Physan, systemic fungicides and listerine on hand but haven't begun any treatments thus far. The brown circular patches and white sunken patches began developing about 3 weeks ago. The latest symptom is the single yellowing leaf with irregular brown markings. It's decline happened rather suddenly.
Any thoughts or suggestions would be greatly appreciated.
Appreciate it. ]]>
There is a dark spot near the center of the pic. It looks sunkan, and looks like it sinks through a couple of layers of the plant.
Just below it there is another dark spot. Thre is also a similar dark mark on the dead end of an old flower stem on the right of the pic, on the underside of the spike end.
I have also noticed very very tiny dark raised spots on the base of the next leaf up and two similar raised tiny spots on one of the leaves. These tiny spots are about 0.5mm (or arround 1/32 of an inch).
The sunken spots are somwhat larger, between 5mm and 8mm (maybe arround 1/4").
The plant also feels somewhat limp compared to what I would expect for my Phals.

I have a few orchids with problems. I'm hoping I can get a bit of guidance here.
The first picture is a Dendrobium that I've had for a about a year. It looked fine until a couple months ago. I noticed spots and yellowing on the new growth. I gave it a physan bath and clipped a few bad leaves. It seemed OK for a while, but now it looks like this. What is it? A disease or fungus?
The second pic shows some nice new roots forming. It wants to live.
The third picture is an Oncidium that I picked up at Lowe's a few months ago. It was mislabeled and on clearance, so I figured I'd try to salvage it. I'm having no luck so far. The psuedobulb on the left was shriveled when I bought it. The middle psuedobulb looked good, but now it seems to be shriveling up as well. The growth on the right has done nothing. It still looks the same as it did at Lowe's.

I noticed one of them had a sort of white "mold" on the foot of the leaf (see attachments)
Should I worry? When I flip over the edge of the leaf it's nice and green. The other side of the leaf also looks normal.
I need some advice on what to do about what appears to be a fungus problem on a couple of 'chids that I've only had for a couple months.
I bought myself a Masd. cyctotega and Porroglossum teaguei in late June with lots of black spots on the leaves which at the time I thought were sunburn. Long story short, the "sunburn" started popping up all over the place and the leaves on which it appeared would eventually dry up and fall off. The spots start yellow, then expand and turn black in the center with a little fuzzy stuff later on. The damage goes all the way through the leaf. Figuring it was a fungal problem, I removed all the affected leaves in the hope that that would solve the problem (I also sprayed some rubbing alcohol onto the porroglossum afterwards), and that didn't leave many leaves I can tell you; that was about a week ago. I thought I'd seen the last of it until a couple days ago when I noticed spots again starting on both plants. Just today I dusted them both with powdered cinnamon as I've heard of it being used as a fungicide, and isolated them from the rest of my collection.
Anyone got any advice for me? Does this even sound like fungus? Any help at all is much appreciated.

The brown powder on the leaf in the last picture is cinnamon I put on the plants.
Anyways, I've spent forever reading on how to take care of it, and it is still dying!
One by one, the leaves turn yellow (starting at the tips and working their way nearer to the center of the plant) and then finally browning and drying up. They are not old leaves...in fact, they are small and newer looking.
no brown speckles or anything like that. I know it isn't getting too much sun (it doesn't even get direct like) and I have been watering it minimally since I noticed the first yellow leaf.
I live in Arizona, so my bedroom is dry and a solid 85 degrees during the daylight hours (bad AC)...Someone PLEASE help me before its too late...
I think I have a black thumb :( ]]>
I have this plant for 5 months. When I bought it, it already had brown tips shown on the old leaves. Now, it's growing three new pseudo bulbs. One is growing at the edge of the pot( all three have new spike coming out). Should I repot and separate it into two pots?
I also noticed that the new leaves has some dark spot at the tips and edges of it. And some new leaves look pleated with unevenly green/whitish color. Today, I found out the root of one new pseudo bulb is turning yellow :( I don't know what's going wrong...
P.S.
It's really hot recently, so I misted my plants a lot often.
I used 29/10/10 to feed my encyclia last time. Before that, I only used rain water.

They tend to like the Catts and the Onc Alliance orchids...the ones with fleshy leaves and they EAT the spikes and the leaves.
Here is my question...what pesticide can I use on the chids to deter them? OR if I can't do that what pesticide can I spray around the shadehouse to keep them out?
I can usually catch them at night after I turn the mister on for a few minutes. They come out and pick a chid to chew on for the evening...then I catch them and kill them with RAID on the sidewalk outside. :evil:
But I want to catch/kill/deter them BEFORE they sit down to dine on my chids.... :evil:
Any suggestions?
I live in Memphis, TN (USA) so a pesticide readily available at Lowe's, Home Depot or WalMart would be helpful. FYI - Physan is not readily available locally, but if this is the one I should use...link for purchase would be helpful too. ]]>
I don't know if I'll be able to get rid of these wicked insects. Today I removed all my Chids from the trees and gave the citrus leaves, trunks, and ground beneath a thorough spraying with Orthene Systemic Pesticide. This is not considered to be an effective treatment and from what I've read there is no tried and true method for killing these bugs. :( Systemics are never recommended for fruit bearing trees but these trees did not set fruit this season. I'm planning on treating the entire yard with diatomaceous earth and will continue to spray the tree and area beneath with systemics and neem oil every week. I'm hoping the DE will kill the larval stages as they emerge from the ground. I don't like to use pesticides but if something isn't done the trees will perish. I need to find an effective pesticide that will penetrate the soil beneath the trees to kill the immature bugs that feed on the roots. If anyone has suggestions feel free to chime in. ]]>
What should I do now? Do I just monitor it very closely for more? I'm a little afraid to repot it as I just got it a month ago and I paid a lot for it. I'm afraid that if I repot I'll disrupt its roots and make it even more unhappy with me...
How far away is far enough away from my other plants? I really don't want these little buggers to spread!
Please help me with my malipoense! This plant is very special to me...
Thanks! ]]>
Thanks, Dana
]]>On close inspection today I noticed that it has since put out 8 new healthy growths. :biggrin:
Can anyone tell from the old leaves what the infection might have been? I think it had originally spread from a jade plant I had sitting right next to it.

If there's anything that can be done to save this orchid, please let me know.
I've attached a few pictures of the orchid below.
Thanks
Nothing flying around, no movement I can see. Just this white fluffy stuff.
Pics attached.
Thanks!

I've been having issues with my orchids this summer. I pride myself on taking great care of them and for some reason this summer they are just not doing well.
I came home from work today and saw a leaf on the floor. A perfect green firm new leaf. It came from my 3 year old orchid which has tons of leaves and roots and air roots. The only suspicious thing i see wrong with it is that the crown looks a bit yellow which is odd. I dont see how it would have crown rot b/c given there are so many leaves the crown is about 4" from the base.
Does anyone know what could be the cause of this. The orchid looks very healthy and has a baby leaf coming out from the center...
Do orchids ever die of old age??
Thank you! ]]>
I have been growing orchids for abou 5 ears now and just this summer I have encountered some issses it seems. It may have even started in early spring. On some of my Phals I have noticed that a spot appears on the leaves and some times it goes through the leaf like a rotting spot other time it just stays ther and makes the leaf lok horrble. It is appearing on thenew growth on 1 plant and the older leaves on 2 other plant. I am thinking it is bactrial. I have had them out on the back deck all summer. However we have had record rain fall here on the east coast NB, Canada so they probly have been getting much wetter then they woudl hae been indoors where they spend the winter. I have attached some photos(photo #3 has water on the leaf but you should be able to see the spot) here I hope you can all see them and give me a helping hand form your vast experince :)

Thanks ]]>
I have attached the pics of one of my rescue phals.
It's always had weird leaves, they are very firm but crinkle sorta (pic 1). They have some dark raised spots (pic2) which I never thought much about (sunburn?) but as it grew a new leaf, the top is speckled and i looked at the underside and it is very brown and weird towards the crown (pic 3 top/pic 4 underside of same leaf) it is growing another leaf and it looks ok so far but i'm starting to wonder if it has a virus or something. They are not soft or mushy although it looks like rott kinda.
I've had the plant about a year and it is fine and the roots are ok...
the leaves just look very odd and i dont want any of my other chids to catch something.
Thanks so much!
At the moment this one is in quarantaine in the shed outside (facing the east morning sun, growing lots of new roots) as I don't want to take any risc.
The flower doesn't seem to be withering yet, but the disease seems to be spreading on the other stem as well. Just for safety, I lifted it away from the other phalaenopsis.
Could you please help me? I've searched the Internet and books, but found nothing like it.
Here are links to the pictures: (Too big to post here)

I'm new to the board and I am hoping you all can help me.
I have 12 phals in my NYC apt. They are indoor plants and have been doing well, I'm not sure what happened, but somehow they all have weird bugs in them. They are all repotted in fresh mix and some are as old as 3 years so I am really confused how this happened...
I have confirmed that I have fungus gnats in many of them and i read about the trick to use a potato to see if you have larvae in the plants (the whole thing really grosses me out but we all love our chids so we do it, right...), which brings me to my question...
I cut the potatoes in half to test if my other orchids had larvae in them, instead of the larvae coming to the potato, i got a whole bunch of these TINY little brown spots that are moving around on it. I have no idea what they are and if they are bad for the plant. I never would have even been able to see them without the potato since they are SO SMALL. I would take a pic but they are so tiny that it wouldn't show. They are the size of the period on the screen.
Has anyone seen anything like this before and should i be concerned??? It really grosses me out that they are all these bugs living in my orchids. I tried watering them with a dish soap mixture but as soon as i did the fungus gnats got worse so i'm letting them dry out...
Can anyone help??
Thank you! ]]>
My name is Brandon and this year is the first year I've tried growing phals outdoors. Primarily I wanted to be outside more and also I thought it would be a nice challenge to further my green thumb skills.
I live in the midwest and we've had some crazy weather patterns here this summer. I got this phal about a month ago, in bloom, as a gift. It sits outside in a constantly shaded area (never direct sunlight) with a fan always blowing air around it. It is potted in sphagnum moss and I do the standard issue watering, never after noon, etc.
It was looking sad last week after the blooms fell off a few weeks ago so I cut the spikes down. A few days ago I checked on it and saw that one of the spikes was getting a bit brown near the crown. I monitored this until today when I finally picked things apart to inspect closer.
For one thing, the brown spike just fell off under a light touch. There were some brown parts near the crown; I tried to trim those the best I could. I noticed some of the roots were a bit brown too; here is a pic (click the link): Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting
With the recent high humidity, do you think there is a possibility of too much moisture?
The next problem I noticed was the underside of one of the leaves. You can see it here: Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting Also, the top side of one leaf has little pock marks, but I received the plant like that.
Finally, here is a pic of how it looks currently in case anybody can spot potential problems better than I can. Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting
Please advise any immediate steps I should take. Thank you. ]]>
Since the plant has been growing I did not give it a lot of attention. The orchid has had new roots, and it actually started a new leaf few weeks ago.
What alarmed me was that in the back of the new leaf there is a brown blotch, and if you touch it with your finger, it feels bumpy. At the same, another leaf appeared with a yellow mark (with a rough texture to it), and I just saw another leaf with bumps in its surface.
I would appreciate some advice, and if you do so, could you provide details? I am a beginner.
Thanks!
Quick question - So I got this phal a few weeks ago. I now notice through the clear pot that I have some smaller mushroom with rhizomes growing. I doused it once with physan 20. Any other suggestions of how to treat? Or what else to do? I let the media dry out completely before watering. Is this from the bark breaking down within the pot? Thanks for your help!
Katie :) ]]>
I recently had/have a rust fungus invasion in the dendrobiums that spread to some vandas in the same area. I have sprayed them twice a week, alternating between three different fungicides; one with copper, thiram and a systemic fungicide. The first two kill the fungus on the surface and the systemic is absorbed by the roots. I also cut off all the infected leaves (they don't ''come back'' so look lousy anyway). After a few days the remaining leaf stubs fall off as do the infected leaves still on the plants.
So although the fungus seems to be under control now, I have to be extremely vigilante to keep it that way. I was gone for 3 months and so the fungal spores really can take over.
Remember that treating with some systemic fungicides cannot be mixed with fertilizers. That one I spray all alone. ]]>
I tried rinsing with water, washing with soap and water, and gently rubbing with Goo Gone on a cloth rag. None of those worked. :((
Anyone have experience with this? Please let me know if you have removed paint without damaging the plant. ]]>
I search on the forum but couldn't identify the kind of bug I have. I only find the small black beetle bugs, but i don't think its the small black beetle bugs.
I find some small, long, skinny, black, wingless bugs on my Dendrobium Orchids. I am wondering what is the cause. I water when the pot is dry, and there is enough light. Also it is planted in a small pot about 4" or so.
This Dendrobium Orchids is my second one that I plant. The frist Dendrobium Orchids has the same problem and there are like 50+ this kind of small bugs on the stems, leaves, so i just throw the plant out, but it happen again on this plant. There are only 2 or 3 noticeable bugs on the leave and stems right now
Also, I use the bark type planting mix to plant them.
Thanks ]]>
I have a leaf with a necrotic spot as well. I thought at first that it was sunburn, but now I see that there are some other spots on the underside of the leaf that make me wonder if it's an infection of some kind. Any advice is very welcome!
Cheers,
Literata

I'm currently in quite the predicament. We've recently had a week long period of cloudiness and dampness. I hadn't realized at the time just how susceptible orchids are to fungal infections (I'm a newbie, this is my first baby :( )
Anyway, I recently surveyed my orchid to see if there were any problems, and this is what i found. I've attached the image of the leaf that I have since removed. It was yellowing and drying off long before the black spots appeared. I apologize in advance for the lacking quality, someone else has my camera at the moment. I just wanted to capture the image for reference purposes.
This is my situation, in my neighbourhood (and all the neighbouring cities for that matter) make it ILLEGAL to have chemical pesticide/insecticide/fungicide. This means that I have no means to purchase Physan 20 or Bayer's 3-in-1. I am currently using "Garden Sulphur Fungicide Miticide", applying a thick paste wherever I see black dots on my baby. I've also sprayed the leaf with same and cut off the flower stem to try and get the plant to focus on getting better. I'm planning to repot it tomorrow, onto new media. I've since placed in a much better ventilated area, turning on all the fans available in my place.
Here is my question, would a topical application of the garden sulphur be enough to combat this infection? If not, is there anything I can use as a systematic treatment to remove the fungus? Again, I have no means to purchase insecticides, and so would have to be able to find the product on a different aisle. Currently, the small black spots are on the actual stalk of the plant, as well as slowly starting to grow out to one leaf so far :((
I'm currently debating mixing just a tad garden sulfur to the potting mix, but decided against it because it didn't sound too good.
PLEASE, PLEASE HELP! Any and all advice would be greatly appreciated.
I'm itching to add a lot more to my collection right now and want to make sure that nothing I have now have any viruses. Immuno strips are on its way. But to be more sure, I want to send some samples for testing in a lab. I know of critter creek but can I send samples from Canada? Or better yet, does anybody know a lab in Canada I can send samples to? ]]>
Anyways, my phal developed some sort of rot in one of the new roots. I treated it with hydrogen peroxide and, foolishly, left the root on the plant. With all the other new roots, I realize now that I should have just cut it off at the first sign of rot. Now the rot has moved up and has formed a sunken black spot just above where the root used to join the plant. It is spreading slowly, mostly back towards where the root used to be.
Sorry for the rambling. I just have to explain every little thing. Here's a pic of the problem. I'll let you look at that instead of going on for another 3 paragraphs. :blushing:

I have a sick phal :(
Some horrible black spots on her, deep ones too.
Anybody know what this crap is?? What happened??
She was SOOOO healthy 2 weeks ago, and then BOOM, this crap come?!
I've used Physan once, but not sure if I'm doing the right thing.
Many of the plants affected are seedlings, although not all.
Any suggestions will be gratefully received !
Thanks.
We have a great relationship! I make sure there are no other spiders in the house, eliminating the competition. And in return he eats every last thing that intends to harm my plants!:)
I DO repot EVERYTHING that I bring into my house just as soon as I get it. Removing the dead roots but more importantly removing any bugs( usually none anyhow).
I have ever only seen 1 mealy on a new plant I had gotten so Im not so sure what he eats, but Im going to attribute the fact that my orchids are (so far as my inspections have gone) bug free to the lil jumping spider!
Perhaps one day I'll give him a name ]]>
After studying plant science for 5 years, I know what virus symptoms look like, and this sadly looks like it. Unless it could be something else? One leaf is severely affected, all the others have only a few spots.
It's living quarantined under a bottle (which was to help with humidity originally) and I'd hate to toss it since there is nowhere in EU where I can get a new one.
]]>Please can you help me?
I enclose photos.
I feel lucky that I knew what they were. A friend had a plal and showed me what they were last month. She said you can't get rid of them throw the plant away.

I am faced with a serious problem with my plants,our wet season has started a week ago with heavy down pour.
Moved lots of my plants from eastern side of our house where the plants will get early morning sun and some direct sun light till 10.30 a.m.
With in two days lots of plants got infected,stalks of leaves turn yellow then leaves drop canes follow the suit.I lost catsms.bulbos epidens and dendrobiums.I have sprayed Phyton-27 and Manzate seperately with wetting agents.Is there any thing I should be doing?
veekay
I have 2 brassavolas, one seems to be unaffected by this (it is a smaller plant), the bigger one, which since a week ago is living on my balcony (towards SE, full sun between 8-11) has several leaves with these spots on them..
I have taken them out little by little, now for the whole summer that will be their home..
I don't know what these are..First I thought they are sunburns, but they show up on smaller, hidden leaves too.
I really really hope this is not a virus :(
Thanks for any thought.

Hello,
I need a little help with this. First I posted it on the Beginners forum and now I'm working on whatever needs to be corrected regarding fertilizer. But just to be sure, could this be a fungus? If so, what should I use and how?

Any chance they are sucking on it's roots?
Should I repot?
How can I get a rid of them?
and what are THEY?

Did it take long for any root development to happen? ]]>
I have a question for for all of you, have any of you guys ever used (or do use) the Earth-Tone Insecticidal Soap by Espoma for treating mealies and spider mites on Phalaenopsis orchids?
It says it is plant based but does anyone know what plant? It doesn't smell like neem and I can't figure out what it is. Is it safe for Phals?
Thanks in advance,
Susan ]]>
It has one flower, but the spike is turning yellow in the top and it's gradually spreading downwards. Any idea why? And what should I do? Cut it off? ]]>

so this is my cattleyas leaves, and as you can see there is some spotting on them.What on earth is it? is it a virus or a fungal infection? Im a bit worried as the worse effected ones, which i have removed, are close to that of these ones. so im wondering is it spreading.

Would you please look at the pictures I've attached to this post, and let me know if you have any ideas on what may have caused the condition and how/if I should address the condition? The first picture shows the brown spots as they appear on top of the leaves. The second shows the brown spots as they appear under the leaves. The third picture shows the new healthy-looking shoot. The fourth picture shows the name of the orchid. The fifth picture shows the location where the orchid resides in my apartment (on a windowsill that faces a small balcony to the south west).
Thank you!
Any thoughts on what these little bugs are and how concerned I should be? Also, any thoughts on what the best orchid medium on the BC coast is best for the conditions? ]]>
found these spots on my cattleya in january, which have been slowly spreading on one but not the other. They had been growing roots vigorously in january but now the root growth has stopped and many of the bulbs have shrivelled. On one of the cattleyas, the brown spots have grown to cover a new shoot (see pic). I peeled back the black sheath and it was clean underneath, but now the black pits are growing into the newly revealed plant tissue near the base. Only the top side of the leaves have been affected, as well as the pseudobulbs, but not the undersides. The pits looks like mite damage but i've had these plants in sphag-n-bag conditions to try to encourage root growth and i haven't seen any insects, plus there's no silvery webbing or anything.
Tried a swab with alcohol and cinnamon in case it was a fungus, with no success. I spot-treated with soap just now, we'll see how that goes. Help?! Any ideas??
So I woke up this morning and checked the bamboo skewer in my catt and I found not only a snail but these very tiny silver bugs! Does anyone know what they are? And how I can treat this infestation? What do I do? :(
Thanks -

I have 4 orchids in 4 pots and 2 of them are flowering but something is eating the petals and they are falling of the stems.
The petals show signs of something eating at them but i cannot see anything around them.
Could you please help me.:((
I have also got some problems with black spots on the leaves NEED HELP.
I have bought that Minimaru 3 weeks ago with a spike. I just checked the spike this afternoon to see whether the bud was going to open or not. I found that there was a White insect on every bud. It's about 0.5cm each. I cut the spike off immediately....threw it to toilet >< really don't know why it stays in an unopened bud. I have tried my best to find the insect's picture. Anyone know what's is it? Please help!!!

But they have taken up residence in my orchids. I have heard about so many different ways to get rid of them, but I need a method of something I can just soak them with. I don't want to repot as I just did that, and dont want to shock them again. preferably something non toxic but will consider it if it WORKS quick.
So just something I can make in a bucket and pour into media to get rid of the lil buggers....
Big thanks fellow orchid lovers.:waving ]]>
[/IMG]I got this orchid in really bad shape & it's been this way for a couple mos. Should I keep it for abit longer or say Good-bye to it. I don't give up easily but-------:((
]]>It started loosing its leaves not long after I got it. I saw it had some bugs in the soil. I got rid of them, but the orchid continued getting worse, loosing leaves. Then the bulbs started turning orange at the base, as you can see in the picture. It also feels a bit soft where it is orange.
Is there any hope?
]]>So i was checking up on my cattelya this morning (i.e. checking my bamboo stick in the bark) and noticed that there were about 10 pin-head sized silver/black bugs walking around on the stick. I checked the entire plant over and they don't seem to be on the leaves or anything but the bark. What are these bugs? How do I get rid of them? Will they harm the plant? If I do need to use a product to get rid of them, is there an environmentally friendly way to do so?
Thanx! ]]>
The lights attract the bugs to their doom very quickly and it only took a minute before catching the first one !!
]]>I have attached pictures of the plant and roots. I tried to get pictures of the bugs, but they are too small and fast for me to get them. :((
