The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of determining when it's the best time to plant radishes is to look at the USDA zone info for Fairbanks.

Planting Calendar for Radishes

Frost tolerance for radishes:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since radishes are very cold tolerant you can plant them much earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant radishes in Fairbanks is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant radishes and expect a good harvest is probably August. You probably don't want to wait any later than that or else your radishes may not have a chance to fully mature. Starting your radishes indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Fairbanks. You should expect an average low temperature of -50°F in the coldest months of winter.

Just be sure to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Fairbanks and it will vary from year to year. Half of the time in Fairbanks you get a frost after May 15 so always be ready to cover your radishes if you have a late frost.
