can I cut back tall fall asters

Springfield, VA

Does anyone know if I cut back tall fall asters now (May), and maybe again later, to keep them shorter when they finally bloom in the autumn? Like what we do with mums?

West Pottsgrove, PA(Zone 6b)

I do, and they still get very tall but they do bloom. I always wonder how late I can get away with it.

I cut them back until July 4th and then stop, otherwise I would sacrifice their pretty flowers. The plants have multiplied like crazy over the years and add so much color by my curbside.

I cut them back the second time by July 15th and still have blooms.

Gosh! I hope you can cut them back!! Hubby just wacked mine off with the mower. LET THE GAMES BEGIN!!!!

Thanks so much to you all for your advice. I have cut them back by about a third and will do so again by the Fourth, then sit back and wait for the fall blooms.
