May Lawn Care on Long Island – How to Keep Your Lawn Healthy Before Summer Arrives

By May, lawns across Long Island are finally waking up after months of winter dormancy. Grass is actively growing, trees and shrubs are filling in, and homeowners are eager to spend more time outdoors. But May is also one of the most important months for setting your lawn up for success before the heat and stress of summer arrive.

At Mickey’s Lawnscapes, we know that the work done in May has a major impact on how your property performs throughout the entire season. Proper mowing, fertilization, irrigation, and preventative care now can help your lawn stay thick, green, and healthy during the hottest months of the year.

Here’s what Long Island homeowners should focus on during May.

1. Establish a Proper Mowing Routine

One of the biggest mistakes homeowners make in spring is cutting grass too short. While it may seem like shorter grass means mowing less often, scalping your lawn actually creates stress and weakens root systems.

During May, your lawn should generally be maintained at about 3 to 3.5 inches tall. Taller grass:

• Shades the soil and retains moisture

• Helps crowd out weeds

• Encourages deeper roots

• Improves drought resistance

Sharp mower blades are equally important. Dull blades tear grass instead of cutting it cleanly, making your lawn more susceptible to disease and discoloration.

2. Fertilization for Healthy Summer Growth

By May, your lawn is actively using nutrients to fuel growth. A properly timed fertilizer application strengthens roots, improves color, and prepares turf for summer stress.

At Mickey’s Lawnscapes, we customize fertilization programs based on soil conditions and lawn type. Long Island’s sandy soils often require balanced nutrient applications that promote steady growth without excessive top growth that can become difficult to manage.

Proper fertilization in May also helps lawns recover from winter damage and strengthens them against heat, drought, and heavy foot traffic later in the season.

3. Weed Prevention and Control

Weeds become aggressive during spring, competing with your grass for nutrients and water. Crabgrass, dandelions, clover, and broadleaf weeds begin spreading rapidly as temperatures rise.

May is the ideal time for preventative weed control treatments. A healthy lawn is naturally one of the best defenses against weeds, which is why fertilization, mowing, and watering all work together as part of a complete lawn care strategy.

Our team evaluates each property individually and recommends treatments that target weeds without unnecessarily stressing your lawn.

4. Monitor Watering and Irrigation Systems

Spring rainfall can be inconsistent on Long Island, so it’s important to monitor moisture levels carefully. Lawns generally need about 1 to 1.5 inches of water per week, either from rainfall or irrigation.

May is also the time to inspect sprinkler systems for:

• Broken heads

• Uneven spray patterns

• Leaks

• Overspray onto driveways or walkways

An efficient irrigation system prevents wasted water while ensuring your lawn receives consistent coverage.

5. Aeration and Overseeding for Thin Areas

If your lawn has compacted soil or thin patches after winter, May is a good opportunity for spot aeration and overseeding. These services help improve airflow, nutrient absorption, and turf density.

At Mickey’s Lawnscapes, we use grass seed blends selected specifically for Long Island conditions. Overseeding helps create a fuller lawn that naturally resists weeds and tolerates summer stress more effectively.

6. Edge Beds and Refresh Mulch

May is also a great time to improve overall curb appeal by refreshing mulch beds and redefining landscape edges. Fresh mulch:

• Helps retain soil moisture

• Suppresses weeds

• Regulates soil temperature

• Improves the appearance of your property

Clean bed edges and properly maintained planting areas make lawns look sharper and more professionally maintained.

7. Inspect Trees and Shrubs for Early Signs of Stress

Trees and shrubs are actively growing in May, making this the ideal time to identify:

• Winter damage

• Dead branches

• Insect activity

• Fungus or disease

Addressing these issues early prevents larger problems later in the season. Our experienced crews evaluate plant health and recommend proper pruning, fertilization, or treatments when needed.

8. Prepare for Summer Heat Before It Arrives

The best summer lawns are prepared before summer actually begins. By the time temperatures rise in June and July, lawns that were neglected in spring often begin showing signs of stress.

A strong May lawn care program builds:

• Deeper root systems

• Better drought tolerance

• Thicker turf coverage

• Improved disease resistance

Taking preventative action now reduces the need for costly repairs later.
