How long does it take for overseeding to work?

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.

Does overseeding your lawn really work?

Overseeding can help you get back to the thick, lush, green lawn you've always wanted. By spreading grass seed over your existing lawn, you can thicken up the thin areas, and your lawn will start to look terrific again. (This is different from reseeding, which is when you start over and plant a completely new lawn.)

How often should I water after overseeding?

Water the over seeded area thoroughly for not less than half an hour. This will make the seed wash deep into the soil. For First week water the lawn three times a day. For second week water two times a day and for the third week once in a day watering is enough.

How long should you wait to mow after overseeding?

After you lay down your seedlings, they'll need time and the right environmental protection to grow. They'll need to acclimate and set roots before the first mow, so during the first two to four weeks post aerating and overseeding, don't mow.

How long does it take for aeration and overseeding to work?

Typically, overseeding 48 hours following aerating is a best practice, as this will give the seed the best chance of getting into the soil.

How Does OverSeeding and Mechanical Seeder's Work For Grass Seeding?

Can you water too much after overseeding?

For best results, water all newly-seeded areas twice daily, beginning the day of seeding. The goal is to keep the seed moist, but to avoid standing water. Too much water will kill the seed. If you are not able to water twice a day, thoroughly water once daily for a longer duration.

Should you water right after aerating and overseeding?

During the first two weeks following your aeration and seeding service, the main goal is to keep the ground/seed moist while the seed begins to germinate. We recommend that you water each day for at least 20 minutes in all areas of the lawn (water the soil to a depth of about 1/4”).

Should I fertilize after overseeding?

Overseeding Maintenance

Always wait until the grass is dry before you mow. Fertilize the lawn about six weeks after you sow the seed. Apply a pound of quick-release nitrogen fertilizer for every thousand square feet of lawn space.

How many times should you overseed?

Make it an annual practice. "Annual overseeding is recommended to thicken lawns and make them more attractive, but also to introduce improved varieties of grass that are hardier, less prone to insects and diseases, and more drought tolerant," explains Mayer.

Should grass be wet or dry when overseeding?

Mow the lawn prior to overseeding. Water the lawn to moisten the soil, but make sure it's not soaking wet. A good rule of thumb is to water the day before you plan to overseed so the soil has a little time to dry.

Will rain wash away overseed?

Typically, yes. Heavy rain often leads to soil erosion, which means the top layer of soil is worn down by water. If you seed right before a rainstorm, your fresh grass seed could get washed away through erosion.

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.

Should I add topsoil after overseeding?

Many think that putting topsoil over the seeds would protect it, but in fact, that will actually suffocate the seedlings rather than doing any good. We suggest that straw, hay, or any other type of mulching material be used.

What is the success rate of overseeding?

Even with this heavy watering, overseeding has an average successful germination rate of just 30%.

Will overseeding work without watering?

It's critical that you properly water your lawn after aeration and overseeding. Not doing so could have negative results such as a lawn that won't grow, wasted money, or needing to re-seed all over again.

Can I overseed every week?

Make at least 3 applications of seed, each a week or so apart. More applications are fine, too. Applying a large amount of seed to the lawn gives the competitive advantage to the perennial ryegrass over the weed seeds which are already lurking in the soil.

How many times can you overseed?

How Often to Overseed. Some lawns that suffer from drought or disease may thin out frequently and need to be overseeded once a year. But for most lawns, you will only need to overseed every few years. Just keep an eye on your lawn, and overseed when it starts looking patchy.

How long does it take for Overseed 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.

How thick should you overseed?

At the appropriate time to overseed (knowing when to reseed a lawn is based on your climate and grass type), start by loading the grass seed into a seed spreader and spread about 16 seeds per square inch of soil. The right seed density will depend on the thickness of the existing lawn, so some lawns might need less.

Should I overseed twice?

It is recommended to fill in a lawn with 50% or more grass coverage. However, at 50% you will likely need overseeding twice to get the lawn to 90-100%. Just throwing seed on your lawn without aerating or working up the soil will have little to no positive effect on your lawn.

What is the best fertilizer to use after overseeding?

Use a slow-release nitrogen fertilizer, such as Milorganite, when overseeding. Mixing Milorganite with the seed not only makes nutrients available to the grass when it needs it, it also makes it easier to see where the tiny seeds have been broadcast. This counts as the fall fertilization.

How long do aeration holes last?

While aeration itself can take just a couple of hours, depending on the size of your commercial property, plugs typically break down in about two weeks.

How much seed needed for 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.

What to do after overseeding lawn?

You want to continue watering once each day until your lawn seeds germinate, which can take 10 to 14 days. Then you can reduce watering to once a day for 30 minutes in each section until that lawn is established. This gives those tender new shoots a chance to grow strong when reseeding a lawn in the fall.

When should I stop overseeding water?

Regardless of what system you use, make sure your newly seeded lawn is getting the right water requirements. Watering can be reduced once the seed has completely germinated after approximately 28 days.
