The Q&A Archives: Annuals - Heathers

Question: Hi, I loved having the purple blossoms all summer with my heathers. I would like to know if it is possible to preserve these over the winter so I can enjoy them again next spring/summer. The leaves are already during brown and almost all of the blossoms have gone. Please advise.

Answer: Most heathers are hardy to zone 5 so it's possible yours will winter over if you protect them with mulch. Wait until after the first frost signals the plant to go into dormancy before placing your protection over the plants. I make cylinders out of chicken wire to place over my plants. Make the cylinder wide enough to accommodate the plant, plus about 6" all around. Secure the cylinder to the ground with pegs and then pile shredded leaves, straw or even pine needles into the cylinder, all around the plant. Six to 10 inches of mulch material should be enough to protect the plant. Hope this works in your garden!
