Just check to see if the regions of the bulb that is turning brownish is soft/mushy.

With Fdk type orchids, these appear to be pretty much indestructable in tropical North Queensland when we keep spider-mites at bay - or under control. I just keep a bottle of "yates anti-rot phosacid" if I spot any signs of rotting activity. And - for spidermites - natra soap spray ..... or natra soap with some pyrethrum added to the mix does the job for me ----- packed into a 'atomiser' type spray bottle --- and I spray the leaves (under and over), bulbs and all.

Is your fdk growing indoors or outdoors? I find that good gentle air-circulation cuts down on the chances of rot. In fact, I've only seen some menacing - and quite concerning leaf rot - that all started with a spidermite attack - not quite sure what happened yet - but which got dealt with very effectively with yates anti-rot phosacid ----- which happened to work on whatever it was causing that. I've never had serious bulb rot before on any of my catasetum type orchids. There was one time only when one bulb (of a relatively new arrival fdk) developed some yellow round patch - getting soft. And then I sprayed yates anti-rot onto it ..... and the patch turned black coloured and remained that way permanently. The bulb had no issue after that. No problem.

The leaf rot came after a spidermite attack, and was affecting my whole set of catasetum type orchids. But ----- as mentioned --- it (the rot) got dealt with very effectively (from the treatment). The spidermites got deal with nicely as well.

Hi! That yates product sounds good, I don't think we have that available here though unless it goes under a different name

The brown bits are pretty hard, I grow them indoors in a cabinet with fans going 24/7, I had spidermites on my outdoor plants.

Whew! thank god! I've drenched it and everything! Thank you for the advice

Leareu ----- it's just under the category of phosphorous acid fungicide ----- so I think anything equivalent to that should be ok. Just optional in case you ever look for anything like that.

Hi everyone,

I got some bad news, so a week ago, my grandma came to visit us and she wanted to take a look at my orchid (I owe my orchid obsession to her and she knew how much I loved this particular orchid)

Anyways, she wanted to take a look so I gave the pot to her and well... She accidentally dropped it, I was screaming on the inside but thought maybe it won't affect the new growth, it was just an accident after all. Well, skip to the present and some spots just aren't look so well (there's browning on one side of the new growth). Another note is that when I was scooping all the dirt back into the pot, I noticed the one root the new growth had had a black tip and so just wondering, should I do anything or just let it do its thing?

Sorry to be a nuisance, this is just a really special orchid to me and I don't know to see it die

Dropping it generally won't be fatal for the orchid.

The main thing is to just provide and maintain the suitable growing conditions. Also - just watch out for those that can't be trusted to hold something firmly and reliably. But ----- for the case of your grandmother --- we will excuse her for that.

Hopefully that little shoot will keep growing and developing nicely. Just keep an eye on it. If it remains nice and green, and keeps getting larger, then that will very nice.

I don’t think there’s much you can do for that one. Looks like it won’t last for much longer. Hopefully I’m wrong though.

I do think that it is safe to say that the problem in the old pseudobulb was not caused by the accident - when these are dormant, they are dry and don't have any particular relationship with the pot.

Learu - for future usage (if needed) ----- keep a bottle of copper treatment, which is not systematic - but can be effective for some cases where some attacking organism (eg. fungus or bacteria) is causing or contributing to rotting issues. LINK

Eg. Yates Liquid Copper

Thanks for the advice everyone, damn, sucks to see that I'm probably going to lose this one. But you live and learn, I'll definitely be on the lookout for copper treatment @southpark!

Just keep monitoring Leareu. If the new sprout doesn't change completely to yellow for a long time, then there may be chances of recovery. And also providing that the existing bulb doesn't deteriorate further and goes all soft/mushy.

With the copper treatment - I just normally pop some of the blue liquid into a spray bottle, and then add the appropriate amount of water - then spray onto the whole plant - avoiding the roots if I can help it. I don't know whether it impacts the roots negatively. At least bunnings NZ has 'liquid copper'.
