Chrysanthemums tend to make it in mild cold which tells us that you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

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

The last month that you can plant chrysanthemums and expect a good harvest is probably September. Any later than that and your chrysanthemums may not have a chance to fully mature. Starting your chrysanthemums indoors is a great way to get them started a couple of weeks earlier.
