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.

In Zone 4a you can figure out when it's possible to plant neeps by referring to the USDA zone info.

Planting Calendar for Neeps

Frost tolerance for neeps:	Not tolerant of frost.
When to plant:	After the last frost.

Since neeps are not cold tolerant it's necessary to wait until after the last frost has passed before you can plant them.

The earliest that you can plant neeps in Zone 4a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant neeps and expect a good harvest is probably August. Any later than that and your neeps may not have a chance to really do well. You can get started a few weeks earlier by starting your neeps indoors.

Last Frost Date

In Zone 4a the average date of last frost happens on May 15. You can expect an average low temperature of -30°F in the coldest months of winter.

Since the USDA zone info for Zone 4a is not always accurate the actual date of last frost changes from year to year. Half of the time in Zone 4a last frost occurs after May 15 so be sure to be ready to protect your neeps in the event of one of those late frosts.
