How do you control weeds after overseeding?

After overseeeding, wait until the turf has been mowed at least two to three times before applying a broadleaf weed control. Use proper post overseeding care to rapidly germinate and establish the turf before weeds can get started. Maintain a moist seedbed through supplemental irrigation .

What to do with weeds after overseeding?

An application of Gordon's Trimec or Speedzone can be applied 28 days after grass seed germination. A fall application of Gordon's Trimec with Uncle's Stikit, spreader sticker or a granular application of Loveland Weed and Feed will be quickly absorbed by the broadleaf weeds and is sure to kill to the roots.

Can I spray for weeds after overseeding?

A general rule of thumb is to wait at least until you have mowed the new grass four times before using any standard postemergent broadleaf herbicide. A standard pre-emergent herbicide should not be applied until at least three to four months after seeding the area.

How do I get rid of weeds in my new grass seed?

If a small area, just manually pull any/all weeds found as they appear. If a larger area, spot treat the visible broadleaf weed foliage with a selective liquid herbicide to completely eliminate the weed (root and all).

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.)

How to CONTROL WEEDS after Seeding the Lawn | Weed Control for New Grass

How soon can you treat for weeds after seeding?

Before applying broadleaf weed control to newly seeded grass, you must wait until the newly sprouted grass has been mowed three times or wait at least 30 days, whichever time frame is longer. If applied too soon after grass germination, broadleaf weed control will kill or weaken young seedlings.

What to apply 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.

How do I take care of my lawn after 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 aerate if I have weeds?

Aeration and seeding will work with weeds present in a yard

Ideally, we all want a weed-less lawn, but if they do appear during the aeration and seeding season, it is best to just wait them out as it is more important to establish the grass than to kill weeds.

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.

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 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.

How long does it take to see results from overseeding?

Believe it or not, you can actually see core aeration and overseeding results on your commercial property in as little as 7 to 10 days. This is when the soil plugs will break down and the seeds will begin germinating and you'll start to see healthier, thicker grass develop.

Can I mow immediately 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.

Can I walk on overseeded lawn?

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.

Does overseeding need to be covered?

To Cover or Not to Cover Seeds

Generally when overseeding lawns, the existing grass provides cover and shade. In poor lawns with lots of exposed dirt, the soil will need to be raked to cover the seed with a thin layer of dirt. If you plan to spread compost, apply the compost first and then seed.

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.

Do I need to fertilize 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.

Can you spray Roundup after seeding?

If you're thinking about applying Roundup® For Lawns to a newly seeded area, you should wait until your new grass is not so new—approximately six weeks. For newly sodded, sprigged, or plugged areas, delay the application of Roundup For Lawns until three or four weeks after your project is completed.

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.

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 I aerate before or after overseeding?

Aeration will help ensure your soil is ready to absorb all of the nutrients and seeds that come its way with topdressing and overseeding. That's why you should aerate before overseeding.

What is the best month to overseed your 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.
