Whether it’s new soil or freshly cultivated soil, it is a prime target for blowing weed seeds to find a home. Don’t worry about the weeds until the grass is about 8 to 10 weeks old. You can apply a weed and feed or spray to take care of the problem after that.
If you have a lot of weeds in your yard, you may want to consider using an herbicide to control them. If you don’t have the time or money to do it yourself, a professional may be able to help you.

Should I spray for weeds before seeding?
Many of our clients ask us if they should plant grass seed or kill the weeds first. The answer is that the weeds should be killed first. Before any grass seeds can grow, the weeds and poor looking grass around the lawn should be killed. If you have a large lawn, you may want to consider using a lawn mower to cut down on weeds.
However, if your lawn is small and you don’t have the time to mow it every day, it may be a good idea to use a weed killer such as Roundup® Weed Killer. This herbicide will kill most weeds, but it will not kill all of them. If you are concerned about the safety of Roundup®, you can purchase it at your local garden center or online at www.RoundUp.com.
How long after seeding can you treat for weeds?
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. Broadleaf weed control will kill or severely damage the new grass if it is applied too soon.
If you choose to apply herbicides, follow the manufacturer’s directions for use. Do not apply more than one herbicide at a time on the same area of grass or grass clippings.
Will new grass choke out weeds?
Abundant, vigorous grass overpowers weeds and denies them the nutrients they need to grow. Not only will proper watering choke out existing weeds, but it will also prevent weeds from growing in the first place. If you’re looking for a way to keep weeds out of your garden, you can use a variety of herbicides to control them.
Some of the most common are glyphosate, dicamba, and 2,4-D. These chemicals work by breaking down the plant’s cell walls, making it easier for it to absorb water and nutrients from the soil. However, they can also be toxic to other plants and animals, so it’s best to use them only as a last resort.
Why are weeds growing in my new grass?
The grass is doomed if you don’t water it and the soil dries out. You can cut it for the first time once it reaches 4-5 inches, but you have to water it three times a week until it gets fully established. I see moss growing on the bottom of the pot from the picture you sent me. This is a good sign that your soil is well-drained.
The next step is to plant your seedlings. You can either plant them directly in the ground, or place them in a pot with a drainage hole. I prefer the latter, because I don’t want to have to dig a hole every time I plant a seedling.
If you’re going to do this, make sure that the hole is large enough to allow the roots to grow through it, and that it’s deep enough so that you won’t be able to see the root ball from the outside. The hole should be at least 2-3 inches in diameter and about 3-4 inches deep.
Can you overseed a lawn with weeds?
Existing weeds won’t be killed by over seeding. New weed growth will be suppressed by a thick, overseeded lawn. If you don’t kill the established weeds, they will take water and nutrients from your grass. If you want to keep your lawn healthy, it’s important to maintain a healthy soil. If you don’t, you’ll end up with a lawn that’s not as healthy as it could be.
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 likely that they will be gone by the end of the season.
Can you seed and spray for weeds at the same time?
You can spray it anytime you want leading up to seed day, and on seed day, but once your seeds germinate, you should NOT spray it again until the new gras has been mowed.
