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.
In addition to getting a high-quality grass seed that matches your climate, you also need to consider your lawn’s unique properties. Look over the area where you intend to seed.
The test results should give you a plan, and maybe a shopping list for your local garden shop. Following application directions carefully, add your soil amendments to restore what it lacks. Till your soil to a depth of about five inches, working the soil amendments in evenly.
Best grass seeds for Southern states
If you have a small area where you plan to seed grass, hand tools are sufficient to do the job. Get in there with shovels and rakes and dig out the old sod and weeds.
When it comes to selecting seeds, you have an ally — the Federal Seed Act. First enacted in 1939 and amended five times since, the Seed Act requires seed sellers to provide consumers with valuable information on the seed’s labels.
In between the North and South is the transition zone, where there are both hot summers and freezing winters. Finding a variety of grass seed that works will be a tradeoff: You either find the most cold-tolerant warm-season grass available, or the most heat-tolerant cool-season grass.
