Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The first chance to plant beets in Seattle can be determined by using the USDA zone info.

When to plant:	Up to 5 weeks before last frost.

Since beets do well in moderate cold you can plant them a little earlier in the year than more sensitive plants.

The earliest that you can plant beets in Seattle 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 beets and expect a good harvest is probably September. You probably don't want to wait any later than that or else your beets may not have a chance to fully mature. If you are starting your beets indoors then you might be able to get away with starting them a little bit earlier.
