How long after overseeding can I fertilize?

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 soon after seeding grass 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.

Should you fertilize and overseed at the same time?

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.

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.

When to fertilize new grass after a renovation

Can you fertilize too soon?

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 goes first fertilizer or grass seed?

Fertilize Before Sowing

New grass seeds are vulnerable, but giving them the proper soil conditions helps them take root and grow. For these reasons, it's necessary to fertilize an area to be seeded before doing anything else.

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 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.

How many times a year 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.

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.

Should I fertilize a 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 you put fall fertilizer on new grass seed?

The next application of regular fertilizer for your new lawn is in the fall before the onset of frost or snow. At this time, you can use a fertilizer that's rich in phosphorous as will promote deep root growth, and help your lawn sustain over the winter.

Should I fertilize after overseeding in the fall?

Your best bet is to feed once in early fall (if you are overseeding, your starter fertilizer counts) and once more about 6 to 8 weeks later, around Thanksgiving. Deliver the nutrients grass needs to get through the winter and come up strong the following year.

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”).

How often do you mow after overseeding?

You mow too soon.

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.

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 fertilize your lawn?

Be careful about fertilizing in late September/early October. Fertilizing late in autumn can delay the hardening of the turf and make it more susceptible to winter injury. For this reason, weed-and-feed fertilizers are not recommended.

Is it OK to fertilize every 4 weeks?

You can reapply slow-release fertilizers every six to eight weeks, while a fast-release fertilizer can be reapplied every four weeks.

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.

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.
