Chrysanthemums in September: the One Step Most Gardeners Miss

Then, after the ground freezes, cut the stems to about an inch above the soil. Mulch lightly with straw or leaves. This protects the roots so your mums come back even bigger next year. You’ve just created a perennial that gets more spectacular with age.
