Good Luck with whichever method you use . . .Geraniums are wonderful plants.
I am glad I decided to spend the extra couple of bucks per plant on my geraniums this year, getting them from the nursery instead of Home Depot. It was worth it, as they grew to twice the HD plants' size and had more and larger flowers. They were (and, until the first frost) are magnificent. Thus, I want to save these gorgeous plants vs. tossing them.
