Overwintering Potted Mums: Mulching and Protection Tips

Hardiness and Risks

Mums tolerate down to 10°F, but subzero temperatures can kill them in pots, where roots are more exposed.

Protection Strategy

• Cut back after frost.
• Mulch heavily with straw.
• During severe cold snaps, cover the entire pot with a blanket.

Outcome

With these precautions, potted mums usually survive and return vigorously in spring.
