One of the ways weed treatments work is by preventing germinating seeds from establishing roots. But these products, known as pre-emergents, can’t distinguish between harmful weed seeds and desirable grass seed you put down. Using these products too close to newly planted seed — in timing or proximity — stops grass seed in its tracks, along with the weeds. Post-emergent weed treatments aimed at existing broadleaf weeds can also injure immature grass seedlings.
Choosing appropriate grass varieties is the first step in ensuring your lawn performs up to your aspirations. Grasses vary widely in their preferences and tolerances, just like other types of plants. Kentucky bluegrass and Bermudagrass, for example, differ significantly in climate and maintenance requirements. Planting grass varieties appropriate to your growing region gives your seed a natural advantage.
Many homeowners think lime is a lawn care necessity, but that doesn’t hold true across the board. Normal lawn care can naturally cause soil pH to drop lower over time, and lime applications benefit lawns that need pH raised. But in some cases, soil pH may already be high. Using too much lime or applying it unnecessarily can be as damaging as failing to add lime when it’s needed.
6. Planting without regard for proper timing
Getting your seeding rates right requires knowing the correct size of the area you need to cover. One of the most common problems grass professionals see is when homeowners misjudge their actual lawn areas and over-apply grass seed or other products, such as fertilizers and herbicides.
Creating a lush, vibrant lawn takes commitment, but the rewards of a successful grass seed project are worth the time and resources you invest. A beautiful lawn can improve your home’s value, benefit the environment and enhance your family’s quality of life. Even if you’re a first-time lawn grower, you can seed right and avoid these common mistakes:
Using the proper amount of seed for your project influences success, whether you’re starting from scratch or overseeding an existing lawn. New lawns or spot repairs take about twice the amount of seed needed for overseeding thin areas. Quality grass seed labels include guidance on optimal seeding rates to maximize your results.
Always read and follow herbicide and fertilizer labels, especially the instructions for use on newly seeded lawns and your grass type. As a general rule, avoid pre-emergent weed treatments at least 10 to 12 weeks before seeding — or longer for some products. After planting, reserve broad-spectrum weed treatments until new lawns have been mowed at least two to three times; for fall-planted seed, that usually means spring.
Weed, Feed or Seed?
Do you have more than 75% good grass however your lawn is thin and weedy without widespread bare spots?
Do you have less than 75% good grass with bare spots larger than a few inches in diameter?
This is a big question in early spring: “My lawn needs everything what should I do first, put down seed or kill my weeds? The reason why this question is tricky is because many of the weed controls will harm new grass seedlings.
Here are your best two options:
