March To-Do List For Zone 3

  • Prune overgrown nonspring-flowering shrubs.
  • Start seeds of onions, tomatoes, edging lobelia (Lobelia erinus), asters, marigolds, cauliflower, cabbage, and brussels sprouts indoors under lights. When seedlings have their second pair of true leaves, transplant them to larger pots.
  • Pot up stored bulbs, such as hybrid tuberous begonias, dahlias, canna (Canna ✕ generalis), and calla lilies (Zantedeschia aethiopica). Set them in the light.
  • Water evergreens growing near the house foundation if the soil is dry. Also, mist the foliage—needles will absorb the much-needed moisture.
