One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Zone 10b you can determine when it's the best time to plant crassula by looking at the USDA zone info.

Planting Calendar for Crassula

Frost tolerance for crassula:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's probably a bad idea to plant crassula until after all chance of frost has passed because they are not cold tolerant.

The earliest that you can plant crassula in Zone 10b 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 crassula and expect a good harvest is probably September. If you wait any later than that and your crassula may not have a chance to fully mature. If you are starting your crassula indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

On average all chance of frost has passed is on January 31 in Zone 10b. In the coldest months of winter you can expect an average low temperature of 35°F.

Since the USDA zone info for Zone 10b is not always accurate the actual date of last frost is different every year. Since half of the time in Zone 10b last frost occurs after January 31 be ready to protect your crassula if you have one of those late frosts.
