One of the best tools that you have as gardeners to help us figure out 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 Antigo you can determine when you can plant radishes by reviewing the USDA zone info.

When to plant:	Up to 7 weeks before last frost.

Since radishes are one of those plants that can tolerate quite a bit of cold weather you can plant them quite a bit earlier in the year than more sensitive plants.

The earliest that you can plant radishes in Antigo is March. However, you really should wait until April 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. You can get started a little bit earlier by starting your radishes indoors.
