And it seems to treat your orchids okay? Little to no phytotoxicity?

I have a couple of plants, notably a rhyncholaeliocattleya that, although it came to be with an injured leaf, the plant is looking worse for the wear after treatment. I fear/wonder if I have mealys living and feasting in the media.

Yes, unfortunately, I didn’t recognize the problem until it was a serious problem. This came from my focus on one area and not on the whole plant. Also, too, I observed some decline, but didn’t readily identify it until I posted here.

estación seca, I like your soaking method, and I believe I can get my plants to a point where this is feasible. Are there orchids you do not recommend for this soapy soaking treatment?

I have never seen any ill effects related to insecticides. I have never treated very sensitive plants.
