Planting Calendar for Chrysanthemums

Frost tolerance for chrysanthemums:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since chrysanthemums are barely cold tolerant you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant chrysanthemums in Valley is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant chrysanthemums and expect a good harvest is probably August. You probably don't want to wait any later than that or else your chrysanthemums may not have a chance to really do well. If you are starting your chrysanthemums indoors then you might be able to get away with starting them a few weeks earlier.
