When and How to Overseed Your Maryland Lawn
No matter how well you try to maintain your lawn, certain uncontrolled factors, like weather, can negatively impact your hard work. Not to worry. Here are some seasonal lawn seeding tips to help bring your lawn back to life after a hot summer in Maryland and Virginia.
Seasonal Lawn Issues
You’ve watered, mowed, fertilized, and still notice lawn issues. Why? A number of reasons, including:
- Weather: Too much or too little rain can negatively impact the roots and a lush lawn.
- Insects: While proper lawn maintenance can help prevent infestations, it’s not a fail-safe.
- Disease: Proper maintenance helps prevent disease as well, but doesn’t guarantee health.
Types of Lawn Seeding
Cool-season grasses, like tall fescue and Kentucky bluegrass, are the best types of grass seed for the Mid-Atlantic areas in Maryland and Virginia. But the seeding method you choose is equally important. Just as there are several factors that contribute to lawn issues, there’s more than one way to help fix it:
- Spot seeding. A quick repair where there’s limited damage in a confined area. Use a rake to break up the dead grass and soil, apply seeds, and lightly press down.
- Overseeding. Planting grass seed over a large area of existing turf to fill in bare spots or increase density. Can be done along with aeration.
- Lawn renovation. When rebuilding or repairing a larger area of grass. Whether you break up the thatch or remove the old soil, it’s a complete overhaul of the lawn.
The Best Time for Overseeding
For Maryland and Virginia, the best time to overseed a fescue lawn is in early fall, typically from mid-September through mid-October. This timing is best due to the cooler temperatures. Fall’s milder days and cooler nights are ideal for fescue seed germination and establishment. Even though the air is cooling down, the soil still holds summer warmth, helping seeds sprout faster. Weed competition is also minimized. By fall, many summer weeds start dying off, giving new grass a better chance at success. Lastly, it encourages better root development. Grass established in fall has the entire cool season to grow strong roots before facing summer heat again.
If you overseed too early, summer heat can stress seedlings. Too late, and frost or freezing temperatures can halt germination before roots develop. At MRW Lawns, we strategically time our aeration and overseeding to ensure you see the best results on your lawn.
Seasonal Lawn Seeding Tips
No matter how you go about seeding your lawn, there are some constants to always keep in mind:
- Use high-quality seeds for high-quality grass.
- Ensure seeds make contact with the soil, or they can easily be blown or washed away.
- Water after seeding to help establish the germination process. Continue to water lightly until the grass is about one inch tall.
- Consider the current season. Seeding works best when done in the late summer or fall. The soil is still warm, but the weather is cool enough not to put stress on the seeds like the harsh winter and summer brings.
- Avoid applying any type of weed control until the new grass is established and has been mowed several times.
