how should i cut back garden phlox for winter– I live in mid to north ohio
I have three plants that were new this spring
When most of the leaves have fallen, cut the stalks down to 2-3 inches. If there was powdery mildew, remove fallen leaves as well. If you are asking about creeping phlox that has gotten too large or starting to be leafless in the center, wait until early spring. Cut an inch off the entire green portion or cut the green portion back by half.
