March 2019 Garden to do Lists. Our suggestions for your March garden projects.


  • Plant trees, shrubs, ground covers, vines, and perennials. 
  • Vegetable Varieties
    • Plant varieties that are cold tolerant for an early summer harvest.
    • Asparagus, broccoli, brussels sprouts, cabbage, carrots, cauliflower, celery, English peas, onions, potatoes, swiss chard, strawberries
  • Ornamentals
    • Plant cool loving annuals
    • Alyssum, calendulas, cannas, daylilies, English daisies, gladiolas, poppies, larkspur, pansies, petunias, pinks, primrose, snapdragons
  • Fruit trees, grapes, pecans and berries
  • This is an excellent time to relocate landscape plants.  Do not trim plants to be relocated. 
  • Divide and transplant summer and fall blooming perennials.
    • Daisies, coneflowers, asters, mums, salvias, etc


  • Turf
    • Use a natural organic fertilizer at app 20lbs per 1000 sq ft for regenerative applications.  If your soil is healthy cut the rate to 10lbs per 1000 sq ft.
    • For pre-emergent control, apply corn gluten meal at 20lbs per 1000 sq ft.   Apply before weed seeds germinate. Corn Gluten Meal Article
    • If your soil is in poor shape and compacted, spray hydrogen peroxide solution.  Mix 32oz of hydrogen peroxide (3%) per gallon of water.  One gallon of water should treat app. 1000 sq ft.  Hydrogen Peroxide will improve soil flocculation (fluffiness and aeration). Hydrogen Peroxide Article
    • Encourage microorganism growth in poor soil by appling dry molasses at 20lbs per 1000 sq ft.
  • Ornamentals
    • Apply earthworm castings, fish meal, alfalfa, or other organic fertilizers around cool season flowers at 10 to 20 lbs per 1000 sq ft.
    • Spray growing plants with organic foliar fertilizers.  We suggest Garrett Juice.  The recipe for homemade Garrett juice is on our website.  Drench newly planted or transplanted plants as well
    • Treat any areas of concern with compost and compost tea.
    • Feed inside plants with coffee grounds and Garrett Juice.


  • Shade and Ornamental Trees
    • Remove dead, diseased and crossing limbs. 
    • Remove limbs that are impeding walking traffic and where necessary to allow light to lower plants.  AVOID PRUNING LOW LIMBS AND FOLIAGE AS THEY ARE NECESSARY FOR TRUNK DIAMETER DEVELOPMENT.
  • Peach and Plum trees should be pruned 40% to 50%.  Prune so to encourage 45-degree growth pattern. 
  • Grapes should be pruned by 80% to 90%
  • Other fruit trees should be pruned as needed.
  • Do not prune crepe myrtles except to remove ground sprouts.
  • Evergreens as summer flowering shrubs as necessary.  Prune to reduce height but try to maintain a natural appearance.
  • Bush form roses should be pruned as needed.  Climbers and roses that bloom only once should be pruned only after they have flowered.
  • Ground covers should be pruned to remove winter-damaged foliage.


  • As needed.

Pest Control

  • Watch for aphids on some plants.  These can be washed away with a water spray.
  • Consider applying beneficial nematodes to your soil to help control grub worms, fleas, fire ants and other pests.
  • Now is the time to start a fruit tree and pecan tree program.  More information is available on our website.

Odd Jobs

  • Check and repair irrigation systems.
  • Check, repair, sharpen and replace garden and lawn tools as needed
  • Top dress and mulch any bare soil areas. 
  • Turn the compost pile.
  • Feed and water the birds


  • Till your soil
  • Scalp your yard
  • Spray any synthetic man-made pesticide, herbicides or fertilizer.
