Insects - Rosemary 'tree'
My recently purchased Rosemary 'tree' is rootbound. As I began to re-pot it I noticed small insects crawling into the rootball. That might explain some of the inner-browning of the branches.
The insects were only visible for a moment, but were too big for spider mites. They might have been aphids. I've scraped the surface soil off, used the hose from the kitchen sink to pressure-wash the foliage, and poured soapy water over the plant twice.
Any ideas on how to eradicate the bugs while not poisoning the plant for cooking-use next spring? The plant came with lots of recipes, but I'll err on the side of caution and give it a couple of trimmings before I use any of the rosemary.
I think that the browning has been caused by either the plant being rootbound or the insects. It's in a sunny southeast window and has been misted and watered regularly since I bought the plant (4 plants make up the conical tree) two weeks ago.
Any other recommendations to help eradicate the 'crawlies'?
