December: Gardening To-Do List


  • Plant your container and Ball & Burlap (B & B) trees.
  • Keep pansies moist, especially when air is cold and dry.
  • Mulch all beds including those around trees to help with moisture retention. Mulch keeps the areas from freezing as deeply.
  • Continue mowing cool-season lawns on a regular basis or when grass is 3-4” tall. Do not cut off more than a third on each mowing.
  • Remove leaves from cool-season grasses or mow with a mulching lawn mower.
  • Continue planting spring flowering bulbs. See Planting Guidelines for details.
  • Continue to control broadleaf weeds in well established warm or cool-season lawns with ferti-lome Weed Free Zone post emergent broadleaf weed killer.
  • If soil is dry, irrigate all plantings, especially broadleaf evergreens and conifers, at least 24 hours before hard-freezing weather.
  • Review the year’s schedule and make plans for next year’s improvements.
