Feeding. I think that's my problem. I have only done generic plant food. I'll have to try orchid food. It's funny how life changes. I never had the collection you had, especially of any one type of plant. But I have gone through years where I had an excessive number of plants by any regular persons standards to not having any but these that have survived neglect. We began traveling out of state a lot and it was too hard to find someone to care for them properly, then I would be disappointed when I returned. Eventually they just dwindled in number. But here I am collecting again.
