The USDA Zone info is a great tool for gardeners to help us figure out 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.

You can determine when it's possible to plant spinach in Zone 2a by using the USDA zone info.

Planting Calendar for Spinach

Frost tolerance for spinach:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Spinach are moderately cold tolerant which means that you can get them planted earlier than other plants that might not handle the cold.

The earliest that you can plant spinach in Zone 2a is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant spinach and expect a good harvest is probably August. Any later than that and your spinach may not have a chance to grow to maturity. If you are starting your spinach 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 May 15 in Zone 2a. In the coldest months of winter you should expect an average low temperature of -50°F.

Just be sure to remember that the actual date of last frost is 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. Since half of the time in Zone 2a you get a frost after May 15 be ready to cover your spinach if you have a surprise late frost.
