How long should I wait to 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.

Should I overseed before or after fertilizer?

Fertilizing After Seeding

Try to overseed within a few days of aerating to ensure the ground is still nice and porous. Follow this with fertilizer either immediately after or within the next three days.

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.

Can I fertilize my lawn after over seeding?

It's best to wait around 4 days after overseeding before you fertilise. Otherwise, the fertiliser may stop the seed from germinating. If you need to do it at the same time, make sure you use a fertiliser developed for young lawns, such as MOOWY's Lawn Starter.

What is the best fertilizer after overseeding?

Fertilize Overseeded Areas

Starter fertilizer, such as Pennington Ultragreen Starter Fertilizer 12-22-8, delivers essential nutrients for new grass. Phosphorus supports vigorous root growth, while nitrogen fuels top growth and greening.

Can you fertilize 2 weeks after seeding?

It is best to apply starter fertilizer just before, or at the same time as planting grass seed. Follow-up at least four to six weeks later with a regular fertilizer. More frequent application can be harmful to your lawn and the environment, so don't overdo it.

What fertilizer can I use after overseeding?

Fertilize Overseeded Areas

Avoid weed & feed products; the pre-emergent herbicides inhibit seed germination. Starter fertilizer, such as Pennington Ultragreen Starter Fertilizer 12-22-8, delivers essential nutrients for new grass. Phosphorus supports vigorous root growth, while nitrogen fuels top growth and greening.

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.

Should you fertilize after aerating and overseeding?

In most cases, aerating is best before laying fertilizer as it allows for more oxygen and deeper growth of grass roots. If you have compact soil or clay soil, it is especially crucial to aerate before so that the fertilizer reaches deeper roots.

Do I aerate or fertilize first?

For best results, aerate the lawn and then spread seed and fertilizer afterwards. Going in this order - aeration, seeding, then fertilizing - allows the seed and fertilizer to fall into the aeration holes and make full contact with the soil.

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 I fertilize my lawn before overseeding?

You may choose to use fertilizer when overseeding your lawn. Fertilizer delivers nutrients essential to young growing grass and optimizes seed germination and quick establishment. The best time to fertilize your yard is right after your aerate it and spread your seeds.

Can you put down too much overseed?

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.

How many times a year should you overseed your lawn?

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 I water immediately 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. It's important to keep in mind that lawn care is a partnership between you and your lawn care company.

Can I just throw grass seed down on existing lawn?

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.)

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.

Should you fertilize when overseeding in the fall?

Fall is the best time. The autumn season comes with a mix of warm soil and cool air, perfect for planting grass seed and allowing time for new grass roots to develop before winter sets in. It is also a good time to fertilize to build stronger, deeper roots for winter, resulting in a thicker, greener lawn next spring.

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.

What is the timeline for overseeding?

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.

Should you always Overseed after aeration?

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.

When should you not aerate your lawn?

It is best to avoid aerating lawns when they are going into dormancy. So, late summer or early fall are too late for warm-season grasses; it is best to aerate in late spring or early summer. For aerating cool-season grasses, stick to early spring and early fall.

Is a spike or plug aerator better for overseeding?

Even spike aerators, which use a solid tine or fork to poke holes, can cause additional compaction in the areas around the holes. For best results, use a plug aerator, which removes a core, or plug, of grass and soil from your lawn.
