If you decide to treat the weeds with chemicals, start by applying the substance to each weed or patch of unwanted growth rather than to the lawn as a whole. This will save as much of your lawn as possible from being overtaken by weeds.
Weeds in new turf may also be the result of low-quality grass seed. Believe it or not, some products may contain seeds for weeds in addition to the grasses they purport to have. Check the package of your grass seed carefully and ensure that it says “weed seeds 0 percent” before you apply it to your yard. This will give you the best shot at a weed-free lawn.
By properly maintaining your lawn, you can avoid the growth of weeds and enjoy lush, beautiful grass. Keep your lawn watered and fertilized if appropriate. Knutsen suggests fertilizing a new lawn between four and six weeks after you plant it. They also suggest that if weeds do crop up before the four to six weeks are up, you can remove them around the eight- to 10-week mark.
Avoiding Future Weed Growth
Keep gardens and wooded areas clear of weeds whenever you can to prevent the spread of weeds into your newly reseeded lawn. If you notice that weeds are beginning to encroach on your grass, pull the weeds as quickly as possible.
Grass with healthy root systems that is thick and fills the space available will act as its own line of defense against invasive weeds. When you see weeds in an established lawn, remove them individually as quickly as possible. This will help lessen the spread.
Growing the perfect lawn takes time and patience and is not a small financial investment. It can be extremely frustrating when just after you’ve finished reseeding your lawn, weeds in new grass begin to peek through. Using weed killer is not the best idea when you are also dealing with fledgling grass, however. You are better off dealing with weeds individually so as to protect the grass around them.
Treating Weeds in New Grass
When it comes to the growth of weeds, Daily Gardener explains that the best defense is a good offense. If you haven’t yet laid your grass seed, be sure all existing weeds are pulled up at the root, including those growing near the area you’re seeding. Use weed killer before seeding your lawn if at all possible.
Depending on the types of fertilizer you’ve used and the potency of the weeds in your lawn, you may find weeds in a newly seeded lawn fairly quickly. One way to prevent this is to carefully remove all existing grass, weeds and topsoil before applying new topsoil and grass seed. Unfortunately, weed pieces and seeds can easily be left behind in the dirt if you do not thoroughly clear your lawn before applying new seed.
However, you can get rid of these weeds just as fast as they have appeared.
The important thing to remember when new weeds appear in your newly sown lawn is not to act hastily – do not apply a Feed, Weed and Moss Killer type product of any kind on a newly sown lawn.
Although this can be frustrating and we can appreciate that a quick solution will be desired, the good news about these types of weeds is that they are largely shallow rooting and should come out with the first mow at the 6-8 week mark after sowing. If they don’t, they should be easy to pull out of the turf.
In short, here’s what you should do if you encounter weeds in your newly seeded lawn:
It might be tempting to apply weed killer the moment you see that first weed pop out. However, if you use weed killer on newly seeded lawn that isn’t mature enough, the grass and weeds may die. It is a much better approach to remove the weeds one by one if there are only a few weeks.
If your lawn is covered with new seedlings, you can skip a day of watering, but you must keep an eye on the grass. If there is a color change from bright green to dull green, water your grass.
It is crucial that you follow the correct practices to keep your seedlings healthy. This includes keeping your seedlings watered and fed. You should always avoid cutting them too early or too short. By providing the best possible beginning to your seedings, you make it very challenging for weeds to invade.
One of the most important things you need to do with newly seeded lawn patches is to give enough water. You need to wet the soil down, reaching at least 6 to 8 inches. However, take care not to water too harshly as it can lead to washing new seeds away or creating puddles.
4. Use a post-emergent weed killer after the second mowing of your lawn.
You can think about using weed killer after giving your lawn enough time to mature, allowing for at least two mowings. If you encounter issues with broadleaf weeds like dandelions, this is the right course of action to take now.
It is crucial that you read the packing when you are looking at seeds. Reading the packing will enable you to know what the contents are, and you should look for seeds that are labeled “weed seeds 0%.” Some packaging will describe weed-free seeds as “other crop seeds 0%”.
However, if there isn’t a color change, your grass is ready for the watering schedule. To find an ideal watering schedule for your lawn, you can stretch the time between watering sessions, with your goal being a schedule of once or twice a week or if you are in a scorching and dry area, as needed. Don’t forget to water deeply when you do water, getting the moisture down 6 to 8 inches.
6. Fertilizing and mowing young seedlings
What should you do to prevent weeds from rooting?
If you are struggling with more extensive roots, it might be helpful to use a hand shovel first. You can use it to dig around the weed, making it easier to remove the entire weed.
