August Organic Maintenance



  • Plant portulaca, purslane, marigold, zinnia, copper canyon daisy, wildflowers and ornamental grasses for immediate color. Many great types of salvia are available. User spider lilies, fall crocus, fall amaryllis, mums, and asters for later flowers.
  • Fall vegetable garden plants, especially the warm weather veggies. 
  • Warm-season lawn grasses as needed – buffalo, Bermuda, St. Augustine, zoysia.
  • Horseherb, liriope, ophiopogon, Persian Ivy and other ground covers in shady areas where turf is struggling.
  •  Wildflower seed if you haven’t planted already.


  • Declining flowering plants to encourage more blooms. Unruly growth from any plants.

  • If your soil is not yet healthy, apply dry molasses at a rate of 10 lbs. per 1000 sq. ft.  Do not fertilize wildflower areas.


  • Water deeply and as infrequently as possible. Your garden and landscape will usually need more water this month than any other.
  • Potted plants and hanging baskets need water daily. Expanded shale and/or lava sand added to the soil as mulch will greatly help hold moisture and reduce watering needs.

  • Chewing insects: Dust natural diatomaceous earth or spray Garrett Juice Plus or garlic pepper tea.  Spray plant oil products such as Bioganic or Eco-EXEMPT if needed. Add 2 ounces per gallon of orange oil or d-limonene for the hard to control insects.
  • Cabbage loopers and other caterpillars: Release trichogramma wasps before pests appear and spray Bacillus thuringiensis (Bt) at dusk with molasses added at 1 - 2  oz. per gallon of spray.
  • Mosquitoes: Spray or mist one of the plant oil products (not pyrethrum) and apply dry, minced garlic at 1 – 2 lbs per 1000 sq. ft.
  • Borers in peaches, plums and other fruit trees: Use the Organic Fruit and Pecan Tree Program (download from Apply d-limonene or orange oil to the affected parts of the trunks.  Mix into of a 50 / 50 solution with water. Seal the holes with Tree Goop.


  • Mow weekly and leave clippings on the lawn.
  • Turn compost pile.
  • Spray weeds in walks, driveways, and terraces with vinegar. Use 10% or 100 grain with 1 oz. of orange oil, 1 tbs. molasses and 1 tsp. of liquid soap per gallon. Carefully spot spray in beds and turf. Do not use vinegar products that are 20% strength or stronger. They are dangerous and may be petroleum based products.
