I live in Toronto and the nights are getting cold. I had to bring my new basil plant indoors. I bought it 3 weeks ago. I have put it in a south facing window. How long will it last indoors.
Last year I was able to keep my rosemary plant alive over the winter in the same southern window.
I also have 3 basil bush plants. Will they last indoors over the winter or do they just produce and die?
