My 20 large pots of over-wintering geraniums.....
I have about 20 large pots of overwintering geraniums in a spare bedroom. They are doing pretty well and some are still blooming on and off. They are getting a bit tall and gangly though.
My question is this. Last year, I had a great survival rate, but most of the geraniums didn't start reblooming outside until almost the end of June. But at that time, they did quite well. I would like to get them blooming much earlier this year.
Someone mentioned cutting them back, but if I cut them back too much, there will be almost no leaves since they are getting long stems. Would they rebloom this summer if I cut them back to the point they don't have leaves?
Also, if I should cut them back, when should I do so? I live in Wisconsin and won't be able to put them out until May. Many thanks in advance for any ideas.
