My chrysanthemums have become quite straggly, is it best to trim them and let the new growth come up from the bottom of the plant? Suggestions appreciated
I usually support mine with canes as they tend to flop. I also move mine into the greenhouse before the first frost - so fairly soon now! - and keep them going until they stop flowering so that I can keep picking them. Once they stop flowering, I cut them back and keep them in the greenhouse until next Spring when frosts are over.
