One of the best tools that you have as gardeners to help us determine your gardening schedule is the 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.

A way of estimating when it's a good idea to plant lettuce is to check out the USDA zone info for Moscow.

Planting Calendar for Lettuce

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

Lettuce can survive in moderate cold which tells us that you can plant them a little bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant lettuce in Moscow is February. However, you really should wait until March if you don't want to take any chances.

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

Last Frost Date

The average date of last frost is April 15 in Moscow. It might get as low as -10°F during the coldest months of winter.

Just be sure to remember that USDA zone info for Moscow is just an average and the actual date of last frost is different every year. Half of the time in Moscow it frosts late in the year after April 15 so just be sure to be ready to cover your lettuce in the event of one of those late frosts.
