One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Zone 13b you can determine when you can plant morning glory by looking at the USDA zone info.

Planting Calendar for Morning Glory

Frost tolerance for morning glory:	Not tolerant of frost.

Morning Glory are not cold tolerant which means that it's important to wait until it warms up after the last frost has passed before you can plant them.

The earliest that you can plant morning glory in Zone 13b 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 morning glory and expect a good harvest is probably November. Any later than that and your morning glory may not have a chance to fully mature. If you are starting your morning glory indoors then you might be able to get away with starting them a couple of weeks earlier.
