One of the first steps you take when you are making a decision about your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The best time to plant sagina in Zone 4a should be determined by looking at the USDA zone info.

Planting Calendar for Sagina

Frost tolerance for sagina:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Sagina are barely cold tolerant which means that you can start planting them slightly earlier than plants that are more sensitive to the cold.

The earliest that you can plant sagina in Zone 4a 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 sagina and expect a good harvest is probably August. You probably don't want to wait any later than that or else your sagina may not have a chance to fully mature. If you are starting your sagina indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 4a. You should expect an average low temperature of -30°F in the coldest months of winter.

Just be sure to remember that USDA zone info for Zone 4a is an average and the actual date of last frost changes from year to year. Since half of the time in Zone 4a last frost occurs after May 15 be ready to protect your sagina if you have a surprise late frost.
