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 figure out when to plant gladiolus by checking out the USDA zone info.

Planting Calendar for Gladiolus

Frost tolerance for gladiolus:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Gladiolus do well in a tiny bit of cold which means that you can plant them just a tiny bit earlier in the year than other frost tender plants.

The earliest that you can plant gladiolus 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 gladiolus and expect a good harvest is probably November. Any later than that and your gladiolus may not have a chance to grow to maturity. Starting your gladiolus indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Zone 13b it never frosts. In the coldest months of winter you should expect an average low temperature of 65°F.

Remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 13b and it is different every year. Since it never frosts in Zone 13b you do not have to be ready to cover your gladiolus if you have a surprise late frost.
