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.

In Lebanon you can estimate when it's a good idea to plant radishes by reviewing the USDA zone info.

The earliest that you can plant radishes in Lebanon 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 radishes and expect a good harvest is probably September. Any later than that and your radishes may not have a chance to fully mature. You can get started a few weeks earlier by starting your radishes indoors.
