Planting Calendar for Garden Mums

Frost tolerance for garden mums:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Garden Mums do well in moderate cold which means that you can plant them a little bit earlier than other plants that might not handle the cold.

The earliest that you can plant garden mums in Pasadena is January. However, you really should wait until February if you don't want to take any chances.

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