Orchid order... are these plants ok??
I made an order from a vendor to pick up at an orchid show, and he gave me the orchids wrapped in paper and plastic, so i didn't get to see them until i got home... and they don't look that healthy to me, to the point where i'm thinking of trying to return them. But i'm relatively new to orchids so i wanted to know your opinion...
The orchids came with a huge ball of soaking wet sphagnum that covered part of the pseudobulbs.
This oncidium barely has any roots, and the psbs are really thin and wrinkly.
this maxillaria has rotten psbs and the roots don't look healthy to me
the two healthier looking plants have this spotting on the leaves that i don’t know if it’s just water damage or something worse. one of them seems to have the only new growth showing signs of rot as well
What do you guys think? am i being picky here, or are some of these plants in bad shape?

Rotting new growths and pseudobulbs are a bad sign. The plants appear to have been kept too wet and rot has set in. I would contact the vendor. You may have been the last stop on a very long tour.
I would cut off all the dead parts, sterilizing your tool between cuts. Treat with fungicide. Try and re-root the remaining bits. Don't become too hopeful.

I see the tag in the background and know the vendor. I have bought many plants from them, some fantastic and some not. The long trip, coupled with the wet moss and dark sometimes leads to rot.
I would cut away the rot and treat the plant, but I would also contact the vendor because that plant does look very sad.

I'm curious who the vendor is. I can't tell from any tag in the pics. Some will refund or replace. If not, try some seaweed (kelp) when soaking the roots as it really helps stimulate new root growth. I find when I get bare root plants from international vendors, the roots seem to be almost always not too great. I attribute kelp to pulling mine thru in almost all cases.

I'm guessing that this is an import. It is quite a bit trickier than buying established plants. The condition is a bit below average for the import, but if you provide a good environment, it will likely recover. I personally wouldn't complain about the condition. I'm not sure which species it is, but they seem to have enough pseudobulbs to get over the acclimation hump. It will possibly drop lots of leaves in the first month. A couple things which may or may not help is Trichoderma, aspirin (try 325mg tablet in 1-2 liter), and rooting hormones (K-L-N, kelp products etc). High air humidity, and keep the media drier to encourage rooting for the first 1-2 month. Getting the optimum temperature could be also important depending on the species.

Those are dire.
In your shoes I would ask for my money back. If they refuse, this is the age where thanks to electronic media, you can make a serious stink on their face book page, etc etc, there will also be business reviews. I certainly wouldn't want to buy from a firm that shipped out stuff like that. it would make me go else where.

Hi Naoki
I've read a few posts and articles about using aspirin on orchids. I'm wondering what benefits you are seeing, what dosage you use (I've heard 1.75 full strength aspirin per 2 gallons water; does this sound right?), and do you apply to the leaves, to the roots, or both?
Similar questions for Trichoderma. Is this in the form of a seed or root innoculant? Would a compost starter innoculant be likely to include trichoderma? How do you mix, apply, and to roots only, or both leaves and roots?
Thanks!

As you probably know, there are quite a bit of scientific evidences showing that Salicylic Acid (SA) is used to signal immune response to wake up. Similarly, SA also helps in stressful conditions such as drought. Aspirin is a modified SA: acetylsalicylic acid (ASA). There are some experiments showing ASA also has similar effects in some cases.
So I use it when the plants are stressed, at an early stage of infection, during deflasking, and when I receive new plants. As with the preventative method, it is difficult to assess the effect. I feel like that some disease seems to stop without cutting the leaves or other chemicals or higher acclimation rate, but it can't be differentiated from a placebo effect (in other words, don't expect too much). 1-4 tablets (325mg) per gallon is probably a reasonable amount. I have used a higher concentration, and I didn't see anything negative. There isn't any study with orchids, so the dosage is a guess from studies with other plants. I spray to the leaf and drench the pot.
There are several strains of Trichoderma, and their effectiveness differs even within the species, T. harzianum (the commonly marketed ones). There is also another species T. atroviride, which is better at a lower temperature. This might be useful for high altitude/cool/cold growing orchids, but I don't have this. So I'm not sure if the compost starter will work or not. I use RootShield (and follow the suggested dosage). I think it is dormant fungal spores, right? I drench the plants. But when I get really weak imports, I soaked them in the Trichoderma solution for a couple hours. The following post by Lars is one of the reason why I tried this method with my recent Malala import:
Importing plants: The effect of Trichoderma on root development
From reading a couple scientific papers, some Trichoderma does indeed seem to have an ability to promote root growth. I have used this only once for the purpose of acclimation. I was expecting that the drop rate of Malala import would be 50% or so from the posts of others, but I have lost only 1 out of 10 plants (another was practically dead on arrival). They have stabilized and started to grow after 2-3 months, but some of them may still die. I'll try this more in the future.
I'm trying a method to home-brew Trichoderma with oat because it is pretty expensive. My first trial didn't go so well, and I haven't found a time to try again.

You should be able to recover the plant provided that you give the right condition. It will take a while to see any bloom, but it will live. I would remove the dead tissues and pour hydrogen peroxide to clean it and let it air dry then soak it in seaweed or kelp solution for a good 30min daily to promote root growth. Good luck

I agree that it's possible they'll recover after you treat as others have advised, I also think you should contact the vendor with your pictures and concerns. Much can go wrong in the process of shipping, especially international, but that doesn't mean the conditions of those plants are acceptable. I'm starting to think more vendors need to ship plants more dry than not... Good luck, keep us posted.
What are these plants btw?
