When to plant:	Up to 3 weeks before last frost.

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

The last month that you can plant chrysanthemums and expect a good harvest is probably September. If you wait any later than that and your chrysanthemums may not have a chance to grow to maturity. If you are starting your chrysanthemums indoors then you might be able to get away with starting them a few weeks earlier.
