Saving flowers damaged by frost
I have an older, larger geranium flowering plant in a pot that has been damaged by frost. (I am in the Yukon) I have it indoors now and most leaves wilted. When should dead parts be cut back and any other tips for resuscitating a damaged flowering plant? thanks, Grant
Since you moved your plant indoors, you can go ahead and prune the damaged material.
