March Garden Tasks and Seed Planting (For Zones 7-8 PNW)

The zone we use for our homestead is 7, rather than what the zone chart claims is 8b. In a previous post I talked about my decision to follow a colder zone here in Maple Valley, Wa. I find that we have cold/wet longer into early spring than other zone 8’s have. The foothills of the Cascade Mountains and Mount Rainier help play into the weather as well. And it gives me more time, in case a heavy rain or late freeze comes. February 2018 went from warm to an Arctic freeze, which is typical weather. March will have longer hours of light (we just cracked 11 hours of daylight in this past week), and the temperatures should slowly get warmer, but will still freeze at night on clear days.

Garden Tasks:

  • Prune rose bushes.
  • Get bare root plants in the ground, such as fruit trees and roses.
  • Plant flower bulbs.
  • Weed beds.
  • Clean out birdhouses, bird baths and bird feeders.
  • Feed existing fruit trees.
  • Turn compost piles.

Seeds To Plant:

To see more on when to seed, and transplant, see here.

Below are seeds you can start in March and or are ready to transplant, which are either colder-weather crops, or need a longer start time. The dates are not set in stone, it is a guide of what week may be most preferable to get them started. With a cold/wet spring, waiting a week or two more before seeding is smart.

Needless to say, the start of March is a good time to have seeds on hand, potting soil and small pots – and a sunny window, greenhouse or grow light system on hand. And if you start them later? It’s OK for many crops. And for temperamental ones like broccoli, you always can grow those as a fall crop, where they often fare better than in spring, if you miss the window, or late winter is too warm/cold.
