When can I plant Clover in Zone 1a

Before planting it is a good idea to find our USDA Zone info to figure out our garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for our area.

In Zone 1a you can estimate when you can plant clover by looking at the USDA zone info.

The earliest that you can plant clover in Zone 1a is June. However, you really should wait until July if you don't want to take any chances.

The last month that you can plant clover and expect a good harvest is probably July. Any later than that and your clover may not have a chance to fully mature. If you are starting your clover indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on June 15 in Zone 1a. In the coldest months of winter we can expect an average low temperature of -60°F.

Remember that our actual date of last frost is an average because it is based on the USDA zone info for Zone 1a and it can change quite a bit from year to year. Half of the time in Zone 1a we get surprised by a frost after June 15 so make sure that you are ready to protect your clover in the event of a late frost.
