Quick Answer: When To Use Grass Seed

Early fall is the best time to seed because of its shorter days, cooler nights, and heavier dews. Your most successful seeding time is usually the 2 weeks before or after Labor Day which gives your new seedlings time to build strong roots before the winter.

When should I put grass seed on my lawn?

The Turfgrass Water Conservation Alliance service recommends overseeding at least 45 days before your average first fall frost. In southern areas, overseed thinning lawns in late spring, as warm-season grasses enter active growth. For winter color, overseed southern lawns in fall.

What month can I plant grass seed?

In many climates, the best time to plant grass seed is in the autumn. The still-warm soil of late August, September, October, or November encourages optimum root growth, while the cooling air temperatures discourage excessive top growth. This is perfect for establishing lawn grasses and promoting extensive root growth.

Can you just sprinkle grass seed on lawn?

Can you just sprinkle grass seed on top of your existing lawn? While it’s possible to simply sow the new grass seed over your existing lawn, taking the time to prepare your lawn beforehand will increase the likelihood of seed germination and improve your end result.

When should I plant grass seed in spring?

Aim to seed early in the season, but wait until daytime temperatures are in the 60 to 75 degree Fahrenheit range. This roughly corresponds to the optimal soil temperatures for cool-season grass seed germination. Spring sunshine and rain both contribute to strong grass growth.

Do I overseed or fertilize first?

Stop fertilizing for at least a month before overseeding. The fertilizer makes your grass grow faster, which makes it harder for the new seeds to take hold. Identify your grass type or the type of grass you want to grow, so you can manage it appropriately.

What happens if you plant grass seed too early?

Grass seed needs the correct soil and air temperature, as well as moisture content, to sprout. Planting it too early in the spring can result in less-than-ideal germination, because the seeds can die off or become unproductive.

Can I plant grass seed in March?

Is March too early to plant grass seed? In nearly all regions, March is too early to plant grass seed. Temperature is a better barometer; wait until days average about 80 degrees before planting grass seed for summer. March is too late to sow cool-season grasses.

Can I plant grass seed in December?

Grass seed can survive the winter, and planting during the winter season is known as dormant seeding. If you put down grass seed in November or December, the seed will just lay dormant until the soil starts to warm in spring. While this comes with risks, it can also be beneficial and save you time on seeding in spring.

Should grass seed be raked in?

Raking is necessary because the seeds need to come in contact with the soil to germinate properly. Grass seed is typically spread on the lawn using a spreader and this does not ensure good contact between seed and soil. This is important because a newly seeded lawn will need to be watered at least every other day.

Should I put topsoil over grass seed?

Grass seed can grow if not covered, but it is usually beneficial to add a layer of compost, topsoil or straw mulch over the top of your seed to keep it moist and help with germination.

Can I sow grass seed on top of grass?

The seed can be mixed with Lawn Topdressing and applied to the lawn jointly. This will save a bit of time and effort working the topdressing and seed into the surface. The seeded area must be kept moist, therefore, water your lawn after 2 or 3 days if no rain has fallen.

What temperature is too cold for grass seed?

If you’re wondering how cold is too cold for grass seed germination use our rule of thumb and check the weather reports. If the daytime temperature is below 60°F then soil temperature is below 50°F, making it too cold; if there is frost or still a danger of frost, then it’s too cold.

Is it OK to overseed in the spring?

If you live in the North and are unable to overseed in the fall, your next best time is the spring. If you live in the South, the best time to overseed is late spring through mid-summer, since warm-season grasses need warmer soil temperatures to germinate.

How do you plant grass seed in the spring?

Plant Grass Seed Put half the grass seeds in a drop or broadcast spreader. Turn the rake so the tines are facing up. Cover the ground with a thin layer of mulch made from wheat straw, if your lawn is uneven and prone to erosion. Water the lawn lightly each day until the grass is 2 inches tall.

Should I till my yard before seeding?

Tilling and properly preparing soil before seeding increases the chances of a healthy, lush new lawn. Tilling also allows better aeration and nutrient absorption for the seeds and young sprouts, bettering the chances of growth than if the yard was reseeded without tilling.

Should you mow your lawn before seeding?

Mow Low. Before overseeding your thin lawn, cut your grass shorter than normal and bag the clippings. After mowing, rake the lawn to help loosen the top layer of soil and remove any dead grass and debris. This will give the grass seed easy access to the soil so it can root more easily after germinating.
