Last fall I bought a beautiful Aster from Home Depot. I planted it and mulched it well and this year it has grown to waist high!
Should I prune it after frost or let it be?
Thank you!!

I'd tend to want to prune it back to make it a more manageable size. You're right in wanting to wait until a frost sends it into dormancy before pruning it back. Enjoy your garden!
