Mint – Spider Mite Control
Q: I have been trying to grow mint indoors. I’m on my fourth plant! At the top of a few of the stems there’s a spiderwebby kind of thing with dots on it.
A: You have made an excellent observation of symptoms! Your mint plant has spider mites.
I think your best bet is to leave your plant outdoors on a deck or porch at the base of your house wall. Mint is a tough plant and it is not usually harmed by winter cold.
Spider mites, on the other hand, are frozen!
Put it in a spot where it gets sunshine during the day but protection from the wall at night. There is no good way to control spider mites indoors in winter. Put the mint outdoors and let nature do the job for you.
