do you quarantine them or treat them in any way before putting them with your existing plants?
I just came back from my very first orchid show. I was very restrained and only bought one Blc. Taiwan Yellow Ball 'Orchis' which seems to be in good condition but seeing as I'm starting to build up a small collection I started thinking that I possibly might need to start treating any new plants I bring into my home to avoid introducing any nasties. What do you think? A quick spray of Physan perhaps? Or not to bother if the plants seem healthy?
