When can I fertilize my lawn 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.

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.

Can I overseed and fertilize the same day?

Applying fertilizer at the same time you seed your lawn is not a recommended idea. Many experts will tell you that doing so you could risk to destroy a large part of your lawn where the soil was heavily fertilized.

Is it OK to fertilize after aeration and overseeding?

After Aeration Overseed and Fertilize

Immediately after aeration, your lawn is ripe for overseeding and fertilizing. The holes provide excellent soil exposure for seeds and deliver fertilizer directly to the roots of your grass. For best results, use high-quality seed and fertilize with Milorganite®.

Should I fertilize while overseeding?

Not only is it possible to fertilize and overseed at the same time, but it's also actually preferable. Here's everything you need to know to ensure your lawn has the healthiest seed growth every time.

When to fertilize new grass after a renovation

Do you fertilize immediately after seeding?

You can apply before seeding or laying sod, or after you plant the new grass seedlings. After planting you should wait six to eight weeks before reapplying the starter fertilizer. If you fertilize too early, it could result in the roots of the seedlings not being able to absorb the nutrients.

Should I Fertilise before or after overseeding?

If your lawn has not been fed in the last 4 months we recommend feeding the lawn before overseeding. The lawn can usually be overseeded 3 to 4 days after applying a general lawn fertiliser, however, you will usually need to wait about 4 weeks after applying a feed, weed & moss killer.

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.

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”).

Can you fertilize 2 weeks after seeding?

Since each lawn is different, you need to visually determine whether your lawn needs additional fertilizer, but most people can expect to fertilize again within three to four weeks of planting - or when the grass is 1 to 1 1/2 inches tall. This encourages deep roots and inhibits weed growth.

Can I fertilize after putting down grass seed?

Apply starter fertilizer only once you've lightly raked your soil and before you sow your grass seed. Once your grass has seeded, the next round should be a regular fertilizer application – this round should only occur four to eight weeks after the first, starter application.

Is it OK to fertilize newly seeded lawn?

If you're starting a new lawn from seed, sod or plugs — or you're doing bare lawn spot repair — a starter fertilizer helps grass get the perfect start. Unlike established lawns, new grass benefits from extra phosphorus, an essential plant nutrient that supports strong, deep roots.

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.

Can you overdo overseeding?

Ignoring recommended seeding rates

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. Too little seed leaves lawns thin or bare.

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.

Should I aerate after overseeding?

2) If you're going to aerate, you'll want to do this beforehand. Typically, overseeding 48 hours following aerating is a best practice, as this will give the seed the best chance of getting into the soil. Aerating will also help to correct problems in your lawn such as thinning.

What do you put on top of grass seed when overseeding?

If you're using grass seed to overseed your lawn instead of Scotts® Turf Builder® Thick'R Lawn™, it's a good idea to rake in a thin, 0.25-inch layer of enriched soil over your lawn to help the seed settle in. Don't put so much down that you kill your existing grass; less than a quarter of an inch is plenty.

How long after fall seeding can I fertilize?

At about 4 to 6 weeks after the seed germinates fertilize the lawn with a high quality turf fertilizer that is predominantly nitrogen. Once turf is 4 to 6 weeks old or older, nitrogen is the most important nutrient for a healthy, attractive stand of grass.

What month should I overseed my lawn in the fall?

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.

How late in fall Can I fertilize newly planted grass seed?

If you're sowing seed, apply fertilizer at seeding time or two weeks after sowing seed. Water lightly after seeding, and continue to water the seeds and plants at least twice a day to keep the soil moist until the grass is actively growing.

Can you fertilize too early?

Fertilizing too soon can induce nutrient deficiencies and off-color areas in your lawn. This is why many lawns have bright yellow areas in early spring. Nitrogen is readily taken in even under cool soil conditions.

What happens if you don't water after overseeding?

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 you walk on overseeded lawn?

You can walk on your new lawn gently, with smooth soled shoes at any time though you should try to minimise how often and not use the same track. You may need to do so for watering or topping up a few patches with seed. You will not harm seed, seedlings or newly laid turf.

Can you overwater when overseeding?

Remember: Do not over-water! Some soil types will get spongy, and walking on it in this condition will leave serious depressions and cause compaction. Trying to correct a yard full of deep footprints is not a chore you want to attempt! The top inch of soil should stay moist at all times.
