Finally I mentioned this to a dear friend who lives in the Midwest, Tom, and who is an accomplished gardener. He said to give the geraniums Miracle Gro. So I gave them Miracle Gro and they grew. They grew and grew. Yet this did not bloom in spite of all of that great fertilization.
Now it is January and the plant is blooming. It is blooming lots and lots and is loaded with new buds getting ready to bloom. Go figure, eh?
