A patchy and weedy lawn is unpleasant and unappealing. Luckily, there are ways you can get rid of the weeds and replant grass seed to have a lush lawn. Before you start, it’s important that you purchase the right type of seed for your environment and you test your lawn so you know which kind of amendments and compost to use. If your lawn is really spotty and full of weeds, you should kill all of the weeds and old grass in your lawn and start over. If you only have a few weeds, you can spot weed and reseed.

To prepare the soil after either method, make sure you till it down to roughly 6 to 8 inches.

Once the weeds—and grass, if applicable—turn brown, it’s time to bust out your rake. Rake up as much of the weeds as you can. Use your tilling fork to pull any extra weeds out and till the soil to prepare it for your amendments and seed.

Weeds come in multiple categories, either broadleaf, grass-like, or grassy.

Step 5: Rake and Till

We recommend using two different types of spreaders. For the majority of the work, you should use a broadcast spreader because they distribute seed evenly, allowing for thorough coverage. But you’ll want to use a drop spreader around the edges of garden beds to make sure you don’t inadvertently drop seed into them.

If your lawn is patchy and full of weeds, it will never be the envy of the neighborhood. What you’re after is a lush, green lawn with even grass and no dandelions poking their way through. That may sound hard to achieve, but it isn’t too difficult if you follow these steps.

You have a choice ahead of you. Do you want to lay down seed or sod? There are pros and cons to each.

Weeds can be broken down further into categories based on their life cycle—annual, biennial, or perennial.
