September 2022 Gardener’s Almanac Checklist

  • Deadhead (cut off) spent blossoms of perennial and annual flowers.
  • Deep water established trees and shrubs about once per month during the heat of summer.
  • Turfgrass only needs 1 ½-2 inches of irrigation per week. See irrigation needs in your area.

Pests and Problems:

  • If tomatoes are not producing, one common reason could be due to hot weather (95°F and above) which causes flower abortion.
  • Blossom end rot (black sunken areas on the end of tomatoes) is common and is caused by uneven watering.
  • Check under leaves of pumpkins, melons, and squash plants for squash bugs.
  • Treat for Corn ear worm when the corn’s silk is approximately ½ long.
  • Spider mites prefer dry, hot weather and affect many plants. Treat for Spider mites by using “softer” solutions such as spraying them with a hard stream of water or by using an insecticidal soap.
  • Spider mites can be identified by shaking leaves over a white piece of paper. If the small specs move…mites.
  • Control Codling moth in apples and pears to reduce wormy fruit. For specific timing see our Utah Pests Advisories.
  • Historically, control of the Greater Peach Tree borer in peaches, nectarines and apricots occurs the first of July. However, for specific timing see our Utah Pests Advisories.
  • Submit a sample to the Utah Plant Pest Diagnostic Lab (UPPDL).
  • Watch for symptoms of turfgrass diseases.
  • Monitor for damaging turfgrass insects.
