I've read that Horticultural Oil is good for controlling thrips. I think it is to late for this year, everything is budding up or flowering, but would like to start next spring. When is the best time to apply it? marric

As a contact, it would help with thrips that are out in the open. But thrips do the most damage while inside buds, where a contact would be useless. And since thrips eggs are laid inside plant tissue, it won't help there, either.

Here is a very informative link about horticultural oil, how to use it, when to use it, and what it does and does not do.
