August Garden Guide

  • Mulch dahlias to conserve moisture and eliminate weeds.
  • Stake plants with heavy blooms.
  • Order spring-flowering bulbs for fall planting.
  • Keep phlox plants deadheaded. Never let phlox go to seed if you want to keep colors true.
  • Start seeds of daisy, coreopsis, sweet william and pansy in peat pots or nursery beds. Transfer to permanent beds in late September. or early October.
  • Cut gladiolus blooms leaving maximum amount of foliage on plants.
  • Transplant and divide iris and day lily.
  • Watch for red spider mites on phlox.
  • In mid-month, take cuttings of coleus, geraniums and other plants for winter houseplants.
  • Plant chrysanthemums for fall color. Fall planted chrysanthemums need extra winter protection.
  • Plant Madonna lily and Japanese and Siberian iris.
  • Continue watering flowerbeds at least once a week during dry periods.
  • Plant or transplant oriental poppies. Do not mulch, as they prefer hot, sun-baked ground.
  • Bring poinsettias indoors.
  • By the end of the month, start withholding water from amaryllis. Amaryllis requires an eight-week period of drought to bloom. Place in cool basement for three-month rest.
  • Sow cover crops in vegetable garden areas not in use.
  • Cut and dry or freeze herbs. Pick herbs just before blossoms open for best flavor.
  • Inspect corn regularly. Corn pests become abundant in mid-August.
  • Keep eggplant and peppers picked so younger fruit develops.
  • Plant late crops of radishes, lettuce, spinach and beets.
  • Mid-August to mid-September is the best time to establish grass seed. Keep soil moist at all times or seed will dry and die.
  • Plant evergreens now through mid-September so they are well established before winter.
  • Remove thatch from lawn if more than one-half inch thick.
  • Tip layer black and purple raspberries for replacement.
  • Fertilize strawberries with 10-10-10 fertilizer applied at 2-3 pounds per 100 square feet. Thin plants if needed.
