Guide to Regrowing Grass after Roundup Damage

Maintaining a healthy and lush lawn can be a challenging task. One of the most common problems homeowners encounter when trying to maintain a beautiful lawn is Roundup damage. Roundup is a herbicide that is used to control weeds, but it can also damage grass and other plants. This guide will provide you with the steps you need to take to regrow your grass after Roundup damage.

Assessing the Damage

The first step in regrowing your grass after Roundup damage is to assess the extent of the damage. Here are some things you should look for:

Signs of Roundup Damage on Grass

  • Brown or yellow patches on the grass
  • Dead or dying grass
  • Stunted growth of grass

Testing Soil pH and Nutrient Levels

The next step is to test the soil pH and nutrient levels. Roundup can affect the pH and nutrient levels of the soil, making it difficult for grass to grow. You can purchase a soil testing kit from a garden center or hire a professional to test your soil.

Checking for Weed Regrowth

It is also important to check for weed regrowth. Roundup is designed to kill weeds, but it can also kill grass. If weeds are growing in the affected area, you may need to treat them with a herbicide before planting new grass.

Preparing the Area for Regrowth

Once you have assessed the damage, the next step is to prepare the area for regrowth. Here are some things you should do:

Removing Dead Grass and Weeds

Start by removing dead grass and weeds from the affected area. Use a rake or a lawn mower to remove the dead grass and weeds.

Loosening Soil and Adding Organic Matter

Next, loosen the soil and add organic matter to the soil. This will help improve soil structure and nutrient availability. You can add compost, peat moss, or other organic matter to the soil.

Choosing the Right Grass Seed for the Area

Finally, choose the right grass seed for the area. Some grasses are better suited for certain climates and soil types. Consult with a gardening expert to determine the best grass seed for your area.

Planting the Grass Seed

After preparing the area, it is time to plant the grass seed. Here are some things you should do:

Choosing the Right Time to Plant

The best time to plant grass seed is in the fall or spring when temperatures are mild. Avoid planting grass seed in the summer when temperatures are high.

Spreading the Seed Evenly

Spread the seed evenly over the prepared area. Use a seed spreader to ensure even coverage.

Watering and Fertilizing the New Grass

Water the new grass regularly and fertilize as needed. Follow the instructions on the fertilizer package for best results.

Maintaining the New Grass

The key to maintaining a healthy lawn is regular maintenance. Here are some things you should do to maintain your new grass:

Regular Mowing and Watering

Mow your lawn regularly and water it as needed. Avoid overwatering, as this can lead to root rot.

Fertilizing and Overseeding as Needed

Fertilize your lawn as needed and overseed if you notice bare patches. This will help fill in any gaps and promote healthy growth.

Dealing with Weed Growth

If weeds start to grow in your lawn, treat them with a herbicide. Be sure to follow the instructions on the herbicide package.

Alternative Methods for Regrowing Grass

If you are not interested in planting grass seed, there are alternative methods for regrowing your lawn:

Using Sod Instead of Seed

Sod is a quick and easy way to regrow your lawn. It is more expensive than grass seed, but it can be installed quickly and provides an instant lawn.

Hydroseeding as an Option

Hydroseeding is a process of applying a slurry of grass seed, fertilizer, and mulch to the soil. It is more expensive than grass seed, but it can be a good option for large areas.

Other Natural Methods to Enhance Grass Growth

There are many natural methods you can use to enhance grass growth, such as:

  • Aerate your lawn to improve soil structure and nutrient availability.
  • Use compost tea to fertilize your lawn.
  • Plant clover in your lawn to improve nitrogen availability.


Regrowing your lawn after Roundup damage can be a time-consuming process, but it is worth the effort. By following the steps outlined in this guide, you can regrow a healthy and lush lawn. Remember to be patient and take good care of your lawn to ensure its long-term health and beauty.
