Before planting it is a good idea to find your USDA Zone info to determine 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.

In Orange you can determine when you can 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 are one of those plants that can tolerate a tiny bit of cold weather which means that you can get them planted just a bit earlier than other plants that might not handle the cold.

The earliest that you can plant gladiolus in Orange 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. You probably don't want to wait any later than that or else your gladiolus may not have a chance to really do well. You can get started a couple of weeks earlier by starting your gladiolus indoors.

Last Frost Date

The average date of last frost is January 31 in Orange. You should expect an average low temperature of 30°F in the coldest months of winter.

Since the USDA zone info for Orange is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Orange you get a frost after January 31 so be sure to be ready to protect your gladiolus in the event of one of those late frosts.
