What to Do in the Garden in March

 Planting and Propagation

  • ✦  Divide hosta, daylilies and mums.

  • ✦  Plant insectary plants such as

    alyssum, phacelia, coriander, candytuft, sunflower, yarrow and dill to attract beneficial insects to the garden. Use this online OSU Extension Service publication as a resource: https://catalog.extension.oregonstate.edu/em9289




  • Maintenance and Clean-up
  • ✦  If needed, fertilize rhododendrons, camellias and azaleas with acid-type fertilizer. If established and healthy, their nutrient needs should be minimal.

  • ✦  Prune spring-flowering shrubs after blossoms fade.

  • ✦  Fertilize caneberries using band fertilizer, broadcast fertilizer, a complete fertilizer or manure.

  • ✦  Protect new plant growth from slugs. Least toxic management options include barriers and traps.

  • ✦  If soil is dry enough, prepare vegetable garden and plant early cool-season crops (carrots, beets, broccoli, leeks, parsley, chives, rhubarb, peas and radishes).

  • ✦  Plant onions outdoors as soon as the soil is dry enough to work.

  • ✦  Plant berry crops (strawberries, raspberries, blueberries, blackberries, currants, gooseberries and other berry- producing crop plants).
