Houseplant pests coming home from nurseries?
I have gone for periods of time with no pests on my houseplants and then in the last 12 months some of them came down with some bad ones, scale on one and something with stickiness all over everything and webs on the branches on another. I'm afraid that I'm bringing this home from nurseries on new plants. I tried organically to get rid of the pests but it came back on me twice, so I've throw every houseplant out (I didn't have a lot) except a few that were in other rooms, like Sanseveria and Cactus which have been pest free.
Winter is coming when the house will be closed up and I want to start over and start a new collection, but I just don't trust the local sources for plants any more. They always look fine in the nursery but it just can't be a coincidence that after 12 months pest free, that suddenly I have serious pests after purchases.
So what do you do if you don't want to bring home pests? It seems that inspection at the time of purchase isn't enough. I was thinking of starting from seed, but that seems like a slow and limited result. Anyone else have any suggestions?
