How does your garden grow? It can be a challenge to keep it growing well as summer heats up. Utah State University Extension’s Gardener’s Almanac provides a checklist of tasks to help your garden, grass and plants grow well in July. Also included are links for tips and further information.










 

July Checklist

  • Start enjoying the tomato harvest.
  • Side dress (fertilize) potatoes in the garden with nitrogen in early July.
  • Harvest summer squash and zucchini when they are still small and tender.
  • Deep water established trees and shrubs about once per month during the heat of summer.
  • Deadhead (cut off) spent blossoms of perennial and annual flowers.
  • Divide crowded iris or daylilies once they have finished blooming.
  • Visit alpine areas for wildflower displays.
  • Remove water sprouts (vertical shoots in the canopy) of fruit trees to discourage regrowth and to reduce shading.
  • Renovate perennial strawberry beds by tearing out old crowns (mother plants) and applying fertilizer to stimulate new runners.
  • Turfgrass only needs 1 ½ to 2 inches of irrigation per week. Click here to learn about irrigation needs in your area.

Pests and Problems

  • If tomatoes are not producing, it 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 corn for corn earworm.
  • 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, you have 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.
  • Click here for instructions on how to submit a sample to the Utah Plant Pest Diagnostic Lab.
  • Watch for symptoms of turfgrass diseases.
  • Monitor for damaging turfgrass insects.
