How to Overwinter and Care for Mums
by Sue Adams
Our winters can be challenging for mums, so to help them survive Hudson Valley winters:
When the foliage has succumbed to frost, cut the plant back to the ground. Apply a thick mulch (chopped leaves, pine needles, etc.) over the plants. When spring arrives and the threat of frost is over, remove the mulch. Simple reminder: When the forsythia bloom, it’s time to remove mulch!
When the plants are 6-8”, remove the top growth, taking it down to three or four leaves up from the base of the mum. This will encourage the plant to produce side branches and create a bushier, more flower productive clump.
