Monthly Gardening Tips

December 2019


  • Gradually cut back on watering trees, shrubs, lawn and gardens.
  • Water annuals, perennials and assorted plants in containers once a week depending on pot size and temperature. (As always, new plantings will require more water the first year.)
  • Winterize sprinkler system as needed and reset timers to once a week.


  • Fertilize cool-season container gardens with a high-phosphorus blooming formula monthly for continuous blooms throughout the winter.
  • Fertilize your cool-season vegetables with a good organic vegetable food.

Yard And Garden

  • Consider a live, potted Christmas tree this year!
  • Plant trees and shrubs now so they will establish good roots during winter.
  • Plant Amaryllis and Paperwhite bulbs for indoor holiday flowering. Decorate with poinsettias and Christmas cactus.
  • Clean your garden area by removing debris and cut back plants to reduce over-wintering pests.
  • Leave foliage on perennials as it will protect the roots during winter.

 Insects And Diseases

  • Bring samples of insects or damaged plants in plastic bags to our pharmacy area for solutions. (We can also identify plants for you!)
  • Rake leaves especially on lawns. Wet leaves can block light and increase the chance of disease.


  • Protect cool-season vegetables such as broccoli, brussel sprouts, cabbage, carrots, lettuce and spinach in cold frames or with frost cloth


  • Clean and winterize gardening tools and store for the winter.
