When summer arrives in South Jersey, your lawn enters its most stressful season. Extended periods of heat, high humidity, inconsistent rainfall, increased foot traffic, and aggressive weed growth all compete against the health of your turf. Without proper maintenance, even a lawn that looked perfect in the spring can quickly become thin, brown, and susceptible to disease.

The good news is that a healthy summer lawn isn't about working harder—it's about working smarter. Following a consistent maintenance routine will help your grass develop deeper roots, resist drought, and stay greener throughout the season.

Here's our complete summer lawn preparation checklist.

1. Water the Right Way

One of the biggest mistakes homeowners make is watering too often.

Frequent, shallow watering encourages grass roots to remain near the surface where temperatures are hottest and moisture disappears quickly. This creates a lawn that's heavily dependent on irrigation and struggles during dry periods.

Instead, water deeply two to three times per week.

Deep watering encourages roots to grow several inches into the soil where temperatures are cooler and moisture remains available longer.

For most established lawns, aim for approximately 1 to 1½ inches of water per week, including rainfall.

Best time to water

The ideal watering window is:

• 5:00 AM – 9:00 AM

Morning watering allows moisture to soak into the soil before the afternoon heat while giving grass blades enough time to dry, reducing the risk of fungal diseases.

Avoid watering during:

• Midday (too much evaporation)

• Evening (creates ideal conditions for fungus)

2. Raise Your Mowing Height

Many homeowners believe cutting grass shorter means mowing less often.

Unfortunately, the opposite is true.

Scalping your lawn removes valuable leaf tissue that the grass needs to produce energy through photosynthesis. Short grass also exposes the soil to direct sunlight, causing it to dry out much faster.

During summer:

• Cool-season grasses should generally be maintained around 3½–4 inches.

• Never remove more than one-third of the blade during a single mowing.

Taller grass naturally:

• Shades the soil

• Holds moisture longer

• Reduces weed germination

• Develops deeper roots

• Improves drought tolerance

3. Keep Your Mower Blade Sharp

A dull mower blade tears grass instead of making a clean cut.

Those torn tips quickly turn brown, making an otherwise healthy lawn appear dry or diseased.

Damaged grass also becomes more vulnerable to:

• Fungus

• Heat stress

• Insect damage

• Disease

Sharpen mower blades every 20–25 mowing hours or whenever you notice frayed grass tips.

4. Know the Difference Between Heat Stress and Lawn Disease

Brown patches don't always mean your lawn needs more water.

Several common issues produce similar symptoms:

Heat Stress

• Large irregular brown areas

• Grass becomes crispy

• Recovers after cooler weather

Drought Stress

• Footprints remain visible

• Bluish-gray appearance

• Soil becomes hard and dry

Brown Patch Fungus

Common throughout South Jersey during humid summers.

Symptoms include:

• Circular patches

• Dark outer rings

• Rapid spreading after rainy periods

Grub Damage

White grubs feed on grass roots below the surface.

Signs include:

• Turf lifts like loose carpet

• Dead patches continue expanding

• Increased animal activity from birds or skunks digging

Correct diagnosis saves both time and money.

5. Stay Ahead of Weeds

Summer weeds compete with your lawn for every available resource.

They steal:

• Water

• Nutrients

• Sunlight

• Root space

Some of the most common weeds found throughout South Jersey include:

• Crabgrass

• Nutsedge

• Clover

• Spotted spurge

• Plantain

The earlier weeds are addressed, the easier they are to control.

Waiting until late summer often means they've already spread thousands of seeds for next season.

6. Feed Your Lawn Carefully

Many homeowners assume fertilizer is always beneficial.

During periods of extreme heat, however, heavy fertilizer applications can actually stress cool-season grasses.

If fertilizer is needed:

• Choose a slow-release product.

• Follow recommended application rates.

• Avoid fertilizing during prolonged heat waves.

Proper nutrition should strengthen your lawn—not force excessive growth during stressful conditions.

7. Check Your Irrigation System

An improperly functioning sprinkler system wastes water and leaves sections of your lawn under-watered.

Walk your property every few weeks and inspect for:

• Broken sprinkler heads

• Clogged nozzles

• Uneven spray patterns

• Overspray onto sidewalks or driveways

• Dry spots

Small irrigation issues often become large brown patches within just a few hot days.

8. Protect High-Traffic Areas

Summer means backyard parties, cookouts, children playing outside, and pets enjoying the yard.

Constant foot traffic compacts the soil, making it harder for water, nutrients, and oxygen to reach the roots.

To reduce wear:

• Rotate play areas

• Use stepping stones

• Avoid repeatedly parking equipment on the lawn

• Keep heavy objects off stressed turf

If areas begin thinning, overseeding in early fall typically provides the best long-term recovery.

9. Monitor Insects Throughout the Season

Several lawn pests become active during summer.

Watch for:

• White grubs

• Chinch bugs

• Sod webworms

• Armyworms

Signs of insect damage include:

• Irregular dead patches

• Increased bird activity

• Turf that pulls up easily

• Grass that fails to recover after watering

Early treatment can prevent widespread damage.

10. Maintain Your Landscape Beds

Healthy lawns don't exist in isolation.

Mulched landscape beds help conserve soil moisture while reducing weed pressure around trees, shrubs, and flowers.

Maintain approximately2–3 inches of mulch, keeping it several inches away from tree trunks and plant stems to prevent rot.

Proper edging also creates a clean, professional appearance while preventing grass from invading beds.

11. Plan Ahead for Fall

Believe it or not, your fall lawn begins with the decisions you make during summer.

Avoid practices that excessively stress the turf now, and your lawn will respond much better to:

• Core aeration

• Overseeding

• Fall fertilization

• Renovation work

Summer maintenance lays the foundation for next spring's healthiest lawn.
