Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

By using the USDA zone info for Zone 10b it's possible to estimate when it's possible to plant streptocarpella.

Planting Calendar for Streptocarpella

The last month that you can plant streptocarpella and expect a good harvest is probably September. Any later than that and your streptocarpella may not have a chance to really do well. Starting your streptocarpella indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 10b the average date of last frost happens on January 31. It might get as low as 35°F during the coldest months of winter.

Always keep in mind that the actual date of last frost is an average because it is based on the USDA zone info for Zone 10b and it changes from year to year. Half of the time in Zone 10b last frost occurs after January 31 so make sure that you are ready to protect your streptocarpella if you have one of those late frosts.
