Aaron I cried when I read what you did for that lady.
Thank you for making her so happy.....truly amazing and inspirational!
From what I can see, it looks like some Cattleyeas and Dendrobiums (more than that, but I recognize a few of those)....some are very very rootbound. They could use repotting on some and a little TLC will bring them around again. They don't look in bad shape, actually, just some sprucing up. How much time and effort do you want to put into caring for these orchids?
There are culture sheets here on OB Forum.
If you repot, soak the beegeebers out of the orchid roots and pots to make the roots somewhat workable. Also the medium used needs to be soaked 24 hours ahead of time.
Is there any orchid greenhouses or perhaps an orchid society nearby who you could contact and perhaps they will walk you through what needs to be done?
What you've done is so kind and you've made my day!
