When can I plant Zucchini in Zone 2a

One of the first steps we take when we are figuring out 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.

By reviewing the USDA zone info for Zone 2a it's possible to estimate when it's a good idea to plant zucchini.

The earliest that you can plant zucchini in Zone 2a 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 zucchini and expect a good harvest is probably August. You probably don't want to wait any later than that or else your zucchini may not have a chance to grow to maturity. You can get started a little bit earlier by starting your zucchini indoors.

Last Frost Date

In Zone 2a the average date of last frost happens on May 15. In the coldest months of winter we can expect an average low temperature of -50°F.

It's important to remember that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 2a and it can change quite a bit from year to year. Half of the time in Zone 2a we get a frost after May 15 so make sure that you are prepared to cover your zucchini if we have a late frost.
