Do you all have any treatments you do when you bring a new plant in? I know you should quarantine. But I mean, such as spray or treat with neem oil or other insecticide on the off chance there are bugs - or do you wait to see if you see any? Do you do an initial fungal treatment when you bring in a plant or only if you see a problem?
Asking because I'm new to this and have ordered a few orchids from 2 different sources that should get here at the same time, so I'm thinking about just putting them together in the same room, because I has that "Catticus pesticus"

that I am more worried about and have only one safe room right now.
