Should I cut back these mums? If so, when? (pictures included)
I'm in need of some plant wisdom. I have two chrysanthemum plants (not sure what they are), and I've heard that they should be cut back in the summer in order to keep them healthy and beautiful for the fall. Problem is, I never know the best time to do the cutting. I certainly don't want to make a mistake and cut them back too late or too early. Every year I chicken out of doing it, but I figured I would go ahead and ask for some advice.
Here are pictures of each of the plants and their stems, just in case that would help in assessing them. Any help would be appreciated!
