This is my first attempt at growing geraniums (or not?) in SW Florida. The plants are almost 3 years old, in a raised planter with good drainage. They used to get morning sun, but I lost the palm (to ganoderma) that gave them afternoon shade. I have never pruned them.
You can see that there are a few very healthy stems in the group, but most look leggy and gnarly. Those gnarly stems feel almost hollow in spite of have a few leaves at the top. And the good stems are connected to the yucky ones.
The leaves and flowers are much smaller than they used to be as well.
