Seeding and Overseeding in Nassau County for a Thicker Lawn

Need seeding and overseeding in Nassau County? Every spring people throw grass seed on bare spots, and every July those spots are bare again. Spring seed has to fight crabgrass and summer heat. We’re Arnol MR Landscaping, a father-and-son crew, and we seed when grass has the best shot at making it.

Seeding and Overseeding

Seeding means planting grass on bare soil. Overseeding means spreading seed over an existing lawn to fill in thin spots. Both need the seed to touch soil, stay damp and get enough sun.

How we do it

  • Mow low and rake: a short cut and a rake let the seed reach the soil.
  • Aerate: seed that drops into aeration holes sprouts better.
  • Seed: the right blend for your sun and shade.
  • Feed: a starter fertilizer to help new roots.
  • Water: light watering once or twice a day until it sprouts.

Sunny lawns

Tall fescue, Kentucky bluegrass and perennial ryegrass blends.

Shady lawns

Fine fescue blends that handle the shade under big trees.

Bare spots

Patches raked, topped with soil and seeded.

Whole lawns

Overseeding across the lawn to thicken it up.

Timing

The best time for seeding on Long Island

Mid-August through September is the best window. The soil is still warm so seed sprouts fast, the air is cooling off and most weeds are done for the year. New grass gets two good months of growing before winter.

After it sprouts

Ryegrass sprouts in about a week. Bluegrass can take two to three. Keep watering lightly until it’s all up, then water less often but deeper. Wait to mow until the new grass is about 3 to 4 inches tall.

Spring seeding

It can work, but it’s harder. Crabgrass sprouts at the same time, and crabgrass preventers stop grass seed too. If you seed in spring, skip the preventer on those spots.

Where we work

Where we do seeding and overseeding in Nassau County

We do seeding and overseeding for homes in East Williston, Garden City, Mineola, East Meadow, Levittown, Bethpage, Plainview, Hicksville, Albertson, Roslyn Heights, Carle Place and Westbury. See every town on our Nassau County towns list.

Under the big oaks and maples found on so many streets here, lawns thin out from shade every year. A fall overseeding with a shade blend keeps those lawns full.

New York allows phosphorus fertilizer when you’re starting a new lawn, which is why a starter fertilizer is fine at seeding time.

Seeding and Overseeding questions

What homeowners ask about seeding and overseeding in Nassau County

Who’s the best seeding and overseeding service near me?

One that seeds in late summer or early fall, picks seed for sun or shade, and aerates or rakes so the seed touches soil. Ask what seed blend they use.

What do I do if my grass seed isn’t growing?

Check that it’s staying damp. Seed that dries out even once can die. Also check if a crabgrass preventer went down recently, and give bluegrass up to three weeks before you worry.

Should I seed or lay sod?

Seed costs less and grows deeper roots. Sod gives you a lawn right away. Our sod installation page has more on that option.

How much does seeding and overseeding cost?

It depends on the size of the lawn and if you add aeration. Text a photo of the lawn for a free quote.
