I’ve heard from a couple of people who wondered how to keep their geraniums over the winter. Unfortunately, I am blissfully ignorant of such matters. I overwinter my geraniums outside. Fortunately, I found a great article on the subject from the University of Illinois Extension:
“It is foolish to try to save diseased plants, but healthy and vigorous plants do have a good chance of surviving the winter with some care,” says David Robson, University of Illinois Extension horticulture educator.
It turns out, the choices for overwintering pelargoniums in cold climates are three:
- Bring them indoors as potted plants
- Start cuttings indoors
- Make them go dormant
Read the article for the details.
