I have just joined this group so I don't know whether this subject has been discussed before. Hopefully someone can help me. I have a dozen geraniums in large pots on my patio. They are all four to five years old and have never been pruned, mainly because I haven't the sllightest idea of how to do that. They are both upright and hanging. I have fed them but not recently. PLEASE, can someone tell me how to prune them. TIA
