Can you use too much grass seed when overseeding?

Quality grass seed labels include guidance on optimal seeding rates to maximize your results. Don't overdo or cut corners. Too much grass seed causes undue competition for resources such as light, water and nutrients, and grass seedlings struggle as a result.

How much seed should I put down when overseeding?

If most of your lawn already has thick grass growth, overseeding will be a general maintenance task. In this case, you should use two to four pounds of seed for every 1,000 square feet of lawn. However, if your lawn has exposed areas of soil, apply four to eight pounds of seed per every 1,000 square feet.

How much grass seed do I need to overseed?

For the best results, calculate your grass seed needs by type of seed and square footage. Otherwise, a general rule of thumb is 3-4 pounds of grass seed per 1,000 square feet for new lawns and 1-2 pounds of grass seed per 1,000 square feet for overseeding.

How much is too much grass seed?

They should be about one-quarter to one-half inch apart (obviously no one expects you to actually measure – just eyeball it). If you sow grass seed too thickly, the plants will outcompete each other and their growth will suffer. If you don't sow them thickly enough, weeds may move in.

Can you over seed your lawn?

Overseeding is spreading grass seed over an existing lawn. Done right, it's a straightforward process that gets results. As grasses mature, thinning is normal—especially if you enjoy your lawn and use it often. Overseeding keeps your lawn competitive and steeped in youth and vigor, without starting over from scratch.

What happens if you put too much grass seed down?

All plants, including grass plants, need adequate soil space for roots to spread and develop. If you put down too much grass seed, you will encourage competition that will cause your grass seedlings to struggle after germination because there will be excessive competition for sunlight, soil nutrients, and water.

How long does overseeding take to grow?

Depending on conditions and type of seed, new grass seed will begin to emerge in 5-7 days after seeding when moisture and soil temperatures are adequate. An overseeded lawn can be fully established in eight weeks or less. Proper watering is critical to successful overseeding.

What happens if you don't rake in grass seed?

If you don't rake in grass seed, the seeds can wash away or blow away from rain and wind. Furthermore, the grass seeds likely won't get deep enough into the soil to sprout. If you don't have a rake, you can overseed and aerate the lawn for similar benefits.

Will grass seed grow if not covered?

Will grass seed grow if not covered? Yes; but there is more to know when seeding your lawn. Grass seed is resilient. Some seeds on the soil's surface will sprout in spite of harsh treatment, but the germination rate will diminish and you will waste your investment and hard work.

Should I cover new grass seed?

Grass seeds can germinate and grow if not covered as long the grass seed is kept moist. However, covering the grass seed with a thin layer of straw mulch, topsoil, or compost will help retain moisture and speed up the germination process.

When should I over seed my lawn?

Hands down, early fall is the best time to overseed your lawn. The absolute sweet spot for most northern regions of the U.S. is August 15 to September 15. That's when daytime temperatures are still warm enough to encourage growth and nights get cooler, giving new seedlings a break from the heat.

Should you fertilize after overseeding?

If you've recently overseeded your lawn, there's no reason to wait to apply fertilizer. The sooner you spread a lawn starter fertilizer on your yard, the sooner it will begin to feed your grass seedlings. If you like, you apply fertilizer the minute you're done spreading your grass seed.

Should I mow before overseeding?

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.

Can I just throw grass seed down on existing 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.

What is the best grass seed for overseeding?

Should you bury grass seed?

Don't bury the seeds any deeper; grass seed needs adequate light to germinate quickly. After raking, pass over the area with a roller, which helps ensure the good seed-to-soil contact your new seed needs.

Can you overwater grass seeds?

There are two things to always remember for watering new grass seed: Not enough water will kill the sprout. Too much water can leave less than ideal results, as well.

Will grass seed grow if it dries out?

Grass seed needs to stay moist every day. If it dries out, the seed will not even have a chance to split open. Grass seed is close to the surface so it can germinate, this is where the soil needs to stay damp.

What happens if I miss a day of watering grass seed?

Missed a Day of Watering Grass Seed: What Happens? In most cases and for most grass seeds, missing a day of watering will not kill it. However, if the ground dries out, and it most likely will to a sufficient degree, the grass seed will halt its germination process.

What to put down after overseeding?

Apply the lawn fertilizer that works best for your type of grass. Slow-release fertilizer provides nutrients gradually, for as long as three months in some cases. Lightly water the lawn immediately after overseeding. For the first several weeks, water the lawn about three to four times a day.

Can I walk on grass after overseeding?

Treat the lawn carefully: Be careful with your new grass, the way you would be careful with any new plants or growth. Until the full lawn is two to three inches in height, do not mow it or walk on it.

How often should I water after overseeding?

You need to keep the soil moist but you don't want to water for too long. This generally means watering twice a day but for a short period of time (maybe 15 to 20 minutes).

How thick should you spread grass seed?

Most species should be planted at a shallow depth of ¼ to ½ inch. Larger seeds can be planted up to 1 inch deep. Most seedings are too deep if you cannot see a few seeds on the soil surface.
