Will asters survive the winter in northern Kentucky? What measures should I take to ensure this?
Asters will generally do nicely in a Kentucky winter. Mulching does provide protection, and we recommend it. It’s good for preventing soil crusting, conserving moisture, and controlling weeds. Don’t go too heavy, though. This can result in too much moisture retention and crown rot. Pine bark, pine straw, wood chips, and a variety of other materials may be used successfully.
