July Garden Checklist: Keep Your Landscape Thriving Through the Summer Heat

July 01, 2026

July is one of the hottest months of the year in North Carolina, but that doesn’t mean your landscape has to suffer. A few simple maintenance tasks can help your lawn, trees, shrubs, and flowers stay healthy through the summer while setting them up for success later in the season.

Here’s what should be on your July gardening checklist.

Water Deeply, Not Daily

One of the biggest mistakes homeowners make during hot weather is watering too often. Frequent, shallow watering encourages weak root systems. Instead, water deeply one to two times per week, allowing moisture to soak several inches into the soil.

The best time to water is early in the morning before the day’s heat arrives. This reduces evaporation and gives plants time to dry before evening, helping prevent disease.

Refresh Your Mulch

If your mulch has faded, thinned out, or washed away during spring storms, July is a great time to freshen it up.

A 2- to 3-inch layer of mulch helps:

Retain soil moisture
Keep roots cooler during extreme heat
Reduce weed growth
Improve the appearance of your landscape beds

Just remember to keep mulch a few inches away from the base of trees and shrubs to prevent moisture buildup around the trunk.

Keep an Eye Out for Heat Stress

Even established plants can struggle during long periods of high temperatures.

Signs of heat stress include:

Wilting leaves that don’t recover by evening
Brown or crispy leaf edges
Premature leaf drop
Drooping flowers

If you notice these symptoms, check soil moisture before watering. Overwatering can be just as harmful as underwatering.

Deadhead Summer Blooms

Removing spent flowers encourages many annuals and perennials to continue blooming throughout the season.

Regular deadheading keeps plants looking neat while directing their energy into producing new flowers instead of seeds.

Watch for Summer Pests

Warm weather brings increased activity from insects like Japanese beetles, aphids, spider mites, and scale insects.

Inspect your plants regularly, especially the undersides of leaves. Catching problems early often allows for simpler treatment before significant damage occurs.

Avoid Heavy Pruning

Resist the urge to heavily prune trees and shrubs during the hottest part of summer.

Instead, remove only dead, damaged, or diseased branches. Save major pruning projects for the appropriate dormant season unless a specific plant requires otherwise.

Feed Containers More Often

Container plants dry out much faster than those growing in the ground. They also use nutrients more quickly.

Water containers daily as needed during extreme heat, and fertilize regularly with a balanced fertilizer to keep flowers colorful and healthy all summer long.
