Weeds are a common occurrence in lawns, and they can be frustrating to remove. Luckily for you, we have put together some helpful tips on how to repair a lawn full of weeds! If you are looking for an easy way to kill weeds without harming the lawn, try using Roundup herbicide. This weed killer is popular because it does not contain harmful chemicals to harm your grass or pets.

If you have a large lot with many weeds in various locations, applying the product daily will keep the weeds under control and prevent them from spreading too much. It would help if you were still vigilant about preventing new weeds from growing by pulling out any flowers or vegetables before producing seeds. There are other methods we have mentioned also.

10 Effective Ways on How to Repair a Lawn Full of Weeds:

1) Hydroseed:

This is a simple and relatively cheap way to repair your lawn. First, apply water to the bare spots with a hose. Then buy seed online or at a local store and broadcast it over the moist ground.

2) Fertilize:

You can kill weeds by fertilizing the soil with phosphorus-rich fertilizer such as 10-52-10. To adequately cover the ground in bare spots, you’ll need to use a spreader and apply fertilizer with it.

3) Topdress:

One way to help your grass grow quickly and inexpensively is to apply topsoil over any bare areas on your lawn. Topsoil is a type of fertile soil naturally created from the breakdown of rocks forming clay. It can be bought from most gardening stores, or you can take it from your property.

4) Plant Grass Seed:

If you have a grassy lawn, you may think this isn’t a way to repair a lawn full of weeds for you. However, many species of grass seed are available at stores and online. Choose one with the same characteristics as your current grass. Then, cover the bare spots by spreading seed with a spreader or just throwing it out into the area you want to cover.

5) Plant New Grass:

Many types of grass can grow in your area. Take a sample to a local nursery and ask them what grass they recommend for your climate and soil conditions. Then, plant the seeds as directed on the package. You may also find sod or new grass plugs at hardware stores and nurseries, but they can be more expensive than seed.

6) Patch With Sod:

Sod is usually stocked at hardware stores and nurseries. It has already germinated and can be cut to fit your lawn area and quickly fix weeds. If you cannot find sod, you may want to try patches of grass plugs or seeds. They are baby grass plants that have been grown mainly for lawn use. To plant, dig a small hole and drop the pin or grains in it, which is covered by approximately an inch of soil.

7) Patch With Artificial Turf:

Artificial turf is made from plastic fibers and can be purchased at local hardware stores and nurseries. Then, it is ready to be laid down in your lawn area. Artificial turf is an inexpensive way of repairing a lawn full of weeds that you want to cover up, especially if bare spots of dirt are showing through.

8) Try a Solar Weeder:

Solar weeders are becoming increasingly popular because they kill the weeds and give off heat to help your grass grow. Plug it into an electrical outlet, and then use the metal bar to brush over any weeds you see in your lawn area. You can buy one at hardware stores or online.

9) Cover With Black Plastic:

Lay black plastic over the bare soil on your lawn to kill the germinating weeds. This is a good way to repair a lawn full of weeds if you don’t want to leave the area empty for an extended period. Instead, leave it down until new grass grows or until next year. However, remove the plastic before the first frost of the year so your lawn doesn’t die.

10) Spray With Herbicide:

Herbicides are chemicals that can kill weeds on contact if they are sprayed directly onto them. To repair a lawn full of weeds with herbicide, you will have to find out whether or not it works on specific weeds that grow in your area. If it does, buy a sprayer and apply the herbicide directly to the weeds you see.

Tips to Prevent Weeds from Coming Back to Your Lawn:

1. Mow your lawn regularly, at the correct height, and ensure your mower blades are sharp so they cut the grass cleanly.

2. Use a high phosphorus slow-release fertilizer to promote healthy solid grass, which is less susceptible to weeds.

3. Apply pre-emergent weed killer to prevent broadleaf weeds on bare soil before germinating.

4. Keep your lawn well-watered so the soil is always moist and weeds have a hard time germinating.

5. Infrequent watering and drought stress make it easier for weeds to germinate and grow, so water your lawn regularly.

6. Weed manually, weeding around the base of your grass without damaging your plant roots.


Using a weed whacker is one of the most common ways to remove weeds from your lawn. Other options include using a manual weeding tool, digging up the weeds and pulling them out by hand, or spraying herbicides on areas with lots of plant growth.

Of course, we all want our yards to look healthy and attractive, but sometimes that takes more than just mowing. It’s essential to maintain your lawn to avoid being overgrown with vegetation and becoming a nuisance.
