The Q&A Archives: When Do I Cut Back Asters

Question: perennial asters... do I cut them back now,how far,
someone told me to do it again in July. Is this info

Answer: You may cut back or pinch perennial asters once or twice in the spring to early summer to make them bushier, and thus flower more heavily. The trimming can also delay the bloom time a little bit and also keeps the plants a bit shorter than normal. Typical timing might be when they reach about six inches tall and again at a foot or so.
