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.
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.
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.
Avoiding Future Weed Growth
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.
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.
Treating Weeds in New Grass
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.
If you plan to mulch your newly laid lawn, avoid the use of hay. Hay is not a clean mulching option and is nearly always contaminated with weed seeds. Instead, choose paper pellets, which are natural, great for retaining water that the grass needs and a good physical barrier against weeds.
How do you know if seeds are weed seed-free?
2. Mulch Matters
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%”.
1. Your Seed Selection is Key
Special attention should always be paid to newly seeded grass. In addition, you should be on the lookout for infestations of weeds because it is much easier to keep an early weed infestation under control than one that has already been established.
