July Gardening

It can be a challenge to keep gardens growing as summer heats up, so Utah State University Extension provides a Gardener’s Almanac to help. The Almanac also includes links for tips and additional information.

July Checklist

·         Start enjoying the tomato harvest.

·         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.

·         Remove water sprouts (vertical shoots in the canopy) of fruit trees to discourage regrowth and reduce shading.

·         Renovate perennial strawberry beds by tearing out old crowns (mother plants) and applying fertilizer to stimulate new runners.

·         Remember that turfgrass only needs 1 ½ to 2 inches of water per week. See irrigation needs in your area.

Pests and Problems

·         Check under leaves of pumpkins, melons, and squash plants for squash bugs.

·         Watch for Mosaic virus in vine crops such as cucumbers and watermelons, and remove infected plants to reduce spreading.

·         Watch for holes in the leaves of petunias, nicotiana, geraniums and other annual flowers from Tobacco budworm feeding.

·         Protect black locust trees (not honey locust) with a registered chemical to prevent locust borer damage.

·         Control codling moth in apples and pears to reduce wormy fruit.

·         Plan for next month, as control for walnut husk fly in walnuts, peaches and apricots usually takes place August 1 and 15.

·         Learn how to identify a hobo spider.

·         Control European paper wasp with traps.

·         Monitor for damaging turfgrass insects.
