Vegetable seedlings growing in pots
  • Start seeds indoors if you live on the coast or in the Willamette Valley. Late February is a great time to start tomatoes for summer!
  • Take this quiet time to do more planning and research.
  • These cold months are great for projects for the garden. Build trellises for your tomatoes out of sticks or re-purposed materials.
  • Explore your sleeping garden. What has changed over the winter?
