Answer: There are several types of Chrysanthemums. Hardy Chrysanthems are perennial plants and the most commonly grown in gardens. The tops die down in the winter but the roots remain alive and produce shoots in the spring. If not pinched back, these shoots will develop flower buds early in the season. To have your mums bloom in the fall, pinch the shoots back to about 8" in June, and pinch them back again to about 6" in July. Your plants can be divided in the early spring after new shoots appear. Each rooted shoot will develop into a new plant.
