A Calendar Guide to Lawn Care in Maryland

Maintaining a lush, green lawn requires year-round care, especially in central and southern Maryland, where the seasons bring distinct challenges and opportunities for growth. A well-structured Maryland lawn care schedule ensures your grass remains healthy through every season. Below is a month-by-month guide from HarborScapes to help you stay on top of essential lawn care tasks and continue making your neighbors jealous.

Winter (December – February)

Winter is a time for preparation and protection. Though the grass is dormant, your lawn still needs attention.

• Avoid heavy foot traffic on frozen grass to prevent damage.
• Keep your lawn free of leaves, debris, and snow mold buildup.
• If you missed fall fertilization, apply a winterizing fertilizer early in the season to strengthen roots.

Early Spring Lawn Care (March – April)

As temperatures rise, it’s time to focus on early spring lawn care as a preparatory phase for growth.

• Start with a light raking to remove any thatch or debris.
• Apply a pre-emergent herbicide to stop crabgrass and various other weeds from growing. Cool season grasses, such as those common in Maryland, require specific care during early spring, including appropriate mowing frequency, aeration, and fertilization.
• Begin mowing once the grass starts growing, keeping blades sharp for a clean cut. Monitoring soil temperatures is crucial; cool-season grasses begin to grow when soil temperatures reach 50°F.
• Overseed any bare spots to promote a thick, lush lawn.

Late Spring (May – June)

Grass is growing at full speed, making this a crucial time for maintenance.

• Apply a slow-release nitrogen fertilizer for healthy growth.
• Mow regularly, keeping the blade height at 3-4 inches to promote strong roots. Ensure that no more than one third of the grass is cut at a time to maintain lawn health.
• Begin watering consistently, aiming for about 1 inch per week.
• Control weeds with a post-emergent herbicide if necessary. Understanding grass species is essential for tailoring your lawn care practices effectively.

Summer (July – August)

The heat can stress your lawn, requiring careful watering and mowing practices.

• Provide your plants with deep watering less often to encourage the development of strong, deep roots.
• Mow higher (around 4 inches) to provide shade for the soil and retain moisture. Ensuring your lawn remains healthy during the summer is vital for its look and for enhancing your outdoor experience.
• Avoid fertilizing during extreme heat to prevent burning the grass. Leaving grass clippings on your lawn after mowing can enrich the soil with nutrients, contributing to a healthier yard.
• Watch for pests and treat as needed to prevent infestations.

Early Fall (September – October)

Fall is the best time to prepare for the next growing season.

• Aerate the soil to allow nutrients and water to reach the roots.
• Apply a fall fertilizer to encourage root growth.
• Tall fescue is a suitable grass type for Maryland lawns.
• Overseed to fill in bare spots and strengthen your lawn before winter. Overseeding is particularly important for cool season lawns and should be done in the fall.
• Continue mowing until growth slows down.

Late Fall (November – December)

As temperatures drop, grass growth slows, signaling time for winter preparation.

• Give your lawn a final mow at a slightly lower height.
• Remove leaves and debris to prevent mold and disease.
• Apply a winter fertilizer if not done earlier in the fall.
• Store lawn equipment properly for the next season.

When Does Grass Stop Growing in Maryland?

Grass growth slows significantly once temperatures consistently drop below 50°F. Soil temperatures dropping below 50°F signal the end of grass growth. In Maryland, this typically occurs in late October or early November. However, root development continues below the surface, making fall fertilization essential.
