When can I plant Garlic in Zone 6a

One of the first steps we take when we are getting a good idea our gardening schedule is find our USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

One way of estimating when it's possible to plant garlic is to refer to the USDA zone info for Zone 6a.

The earliest that you can plant garlic in Zone 6a 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 garlic and expect a good harvest is probably September. Any later than that and your garlic may not have a chance to really do well. If you are starting your garlic indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 6a the average date of last frost happens on April 15. In the coldest months of winter we can expect an average low temperature of -10°F.

Since the USDA zone info for Zone 6a is not always accurate our actual date of last frost is different every year. Half of the time in Zone 6a last frost occurs after April 15 so make sure that you are ready to cover your garlic in the event of a late frost.
