how to prevent weeds when seeding lawn

If you find that the weeds are recurring past the 6-8-week mark, you may wish to consider using a selective herbicide to spot spray your weeds. Some weed killers such as glyphosate (Roundup) kill more than just weeds, so it is important to not apply these as if they are not done precisely, they can kill your grass. Shop bought selective weed killers will recommend when to apply their product and how often and you should read the instructions thoroughly and adhere to them.

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.

In short, here’s what you should do if you encounter weeds in your newly seeded 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.

If you find that when the lawn is at least six months old and has been taken over by weeds or moss, you can use a Feed, Weed and Moss Killer product.

How to prevent weeds when seeding lawn

It is not a good idea to place the removed weeds in your composter because you could risk spreading weed seeds.

Healthy grass that is flourishing doesn’t leave any space for weeds to creep in. It is true that when your seedlings are barely just sprouting, they can’t do much against the weeds themselves. However, by proper nurturing, they will grow quickly and healthily, and before you know it, there isn’t any space left for weeds to fester.

How do you know if seeds are weed seed-free?

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.

3. Avoid using weed killers too soon.

If you are keen to use mulch, we recommend that you use paper pellets instead. Not only do they protect the new seeds, but they help hold water, and they block weeds from rooting.

What should you do to prevent weeds from rooting?

People used to use hay mulch years ago, but it has a very high contamination rate when it comes to weed seeds, so you should never use hay mulch.

4. Watering

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.

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.
