The USDA Zone info is a great tool for gardeners to help us determine 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.

One way of estimating when it's possible to plant gladiolus is to refer to the USDA zone info for Carson.

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 can survive in very little cold which means that you can plant them slightly earlier in the year than other plants that might not handle the cold.

The earliest that you can plant gladiolus in Carson 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 gladiolus and expect a good harvest is probably September. Any later than that and your gladiolus may not have a chance to really do well. You can get started a little bit earlier by starting your gladiolus indoors.

Last Frost Date

The average date of last frost is January 31 in Carson. It might get as low as 35°F during the coldest months of winter.

Since the USDA zone info for Carson is not always accurate the actual date of last frost will vary from year to year. Half of the time in Carson it frosts late in the year after January 31 so always be ready to cover your gladiolus in the event of one of those late frosts.
