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 figuring out when it's possible to plant celosia is to use the USDA zone info for Carson.

Planting Calendar for Celosia

Frost tolerance for celosia:	Not tolerant of frost.
When to plant:	After the last frost.

It's not a good idea to plant celosia until after the last frost when the weather gets warmer because they require warm weather.

The earliest that you can plant celosia 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 celosia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your celosia may not have a chance to fully mature. You can get started a little bit earlier by starting your celosia indoors.

Last Frost Date

On average the last frost is on January 31 in Carson. You should expect an average low temperature of 35°F in the coldest months of winter.

Always keep in mind that USDA zone info for Carson is not always accurate and the actual date of last frost changes from year to year. Half of the time in Carson you get a frost after January 31 so just be sure to be ready to protect your celosia in the event of a surprise late frost.
