The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

It's a good idea to figure out when it's the best time to plant nasturtium by reviewing the USDA zone info for Zone 11a.

Planting Calendar for Nasturtium

Frost tolerance for nasturtium:	Not tolerant of frost.
When to plant:	After the last frost has passed.

You should not plant nasturtium until after the last frost because they require warm weather.

The earliest that you can plant nasturtium in Zone 11a 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 nasturtium and expect a good harvest is probably November. You probably don't want to wait any later than that or else your nasturtium may not have a chance to really do well. You can get started a couple of weeks earlier by starting your nasturtium indoors.

Last Frost Date

In Zone 11a it never frosts. In the coldest months of winter you should expect an average low temperature of 40°F.

Since the USDA zone info for Zone 11a is not always accurate the actual date of last frost can change quite a bit from year to year. Since it never frosts in Zone 11a you do not have to be ready to protect your nasturtium if you have one of those late frosts.
