March To Do List

  • Prune winter-flowering vines and shrubs after blooming.
  • Plant summer and fall blooming bulbs.
  • Spray fruit trees and roses with dormant oil if you haven’t already done so. (Please note that Linda Gilkeson doesn’t spray dormant oil or lime sulphur routinely because they kill beneficial mites and insects. However, if a tree had a pest or disease problem in the previous growing season that could be controlled with dormant sprays, then she does spray that tree.)
  • Plant ground covers, grasses, roses, fruit trees, perennials, shrubs, trees and vines.
  • Plant warm season vegetables.
  • Start feeding your houseplants with an organic fertilizer.
  • Start feeding your trees, shrubs, perennials and vines with an organic fertilizer.

  • Prune forsythia and grey-leafed plants like lavender, lavender-cotton and senecio.
