  • Check the yard for winter damage i.e. heaved plants and broken branches.
  • Start tomatoes, lettuce and other fast growers indoors later this month.
  • Prune summer flowering shrubs and vines.
  • Order summer-flowering bulbs
  • Loosen up packed winter mulch and press back heaved perennials.
  • Make plant markers for the upcoming season.
  • Make homemade seed tapes.
  • Plant annual flower seeds indoors.
  • Adjust guy wires on trees. Check for girdling which will stunt growth
