One of the best tools that you have as gardeners to help us estimate 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.

One way of determining when it's possible to plant lettuce is to consult the USDA zone info for Bellevue.

Lettuce do well in a little bit of cold which means that you can plant them a little earlier in the year than other frost tender plants.

The last month that you can plant lettuce and expect a good harvest is probably September. You probably don't want to wait any later than that or else your lettuce may not have a chance to really do well. Starting your lettuce indoors is a great way to get them started a couple of weeks earlier.
