Love Your Lawn? Follow These Guidelines
Americans are not bashful when it comes to expressing their love of lawns — it has been estimated that there are more than 40 million acres of lawn in the United States. But if you really want to show your lawn some love, you’ll have to do more than mow it. If you’re starting from scratch, you’ll need to learn about your soil and climate, and then decide between sod, seed and a lawn alternative. If you are working with an existing lawn, you’ll want to familiarize yourself with the proper way to water, fertilize and eliminate (or better yet, prevent) unwanted weeds.
Before you decide on a Kentucky bluegrass, Bermuda or rye, find out which grass is best for your climate by consulting the U.S. Department of Agriculture (USDA) plant hardiness zone map. Perform a soil test to see if you need to make any amendments before planting seed, and then follow these guidelines:
- Till the soil and remove weeds, rocks and plants. Consider adding fresh topsoil mixed with an organic material to improve water retention, and a fertilizer to stimulate germination.
- For small areas you can sow the seed by hand; for larger areas use a seed spreader. Cover the seeded soil with straw to protect the seeds and help them retain moisture. Section off the area to avoid foot traffic.
- Water daily and do not mow the grass until it is at least 3-inches high. Water less frequently as the grass matures.
Laying sod is a great way to have a lawn without the wait, but it’s a big job. It’s best to lay sod during cooler weather so the grass can take root and avoid the risk of burnout. (Fall or spring are typically the best times of year in the North; spring is ideal in the South.) Familiarize yourself with how to lay sod before deciding if it’s right for your lawn.
Lawn alternatives provide as much greenery and coverage as a regular turf but can be lower maintenance, hardier and even scent-filled. There are many varieties to consider — from micro clover to Corsican mint — so be sure to check to see which is best for your lawn, climate and upkeep.
Most lawns require about 1 inch of water per week. It’s better to give your grass a good soak every three days than to water a little bit every day. Your lawn will tell you when it needs watering, provided you know the signs. As you walk over the grass, your footsteps should readily disappear; if they don’t, you need to water. A bluish-green color and curling glass blades are also indicators of dehydration.
- Watering less frequently encourages roots to grow downward (in search of water), which makes your lawn more stable.
- In most climates, a deep, thorough watering twice a week should be enough to keep your lawn happy.
- Water your lawn in the early morning, so there will be less evaporation. Grass will also have a chance to dry out before the sun starts beating down.
Grass requires small amounts of many nutrients (calcium, magnesium and sulfur, to name a few). Macronutrients like nitrogen, phosphorus and potassium are needed in larger quantities. A soil test performed by your local extension office will reveal what your lawn needs to succeed. The results of the test will include a range of information, such as your soil’s pH.
- Cool-season grasses (including Kentucky bluegrass and tall fescue) benefit most from fertilizer in the fall, at which time the added nutrients go a long way toward bolstering root growth.
- For warm-season grasses (including zoysia and Bermuda), springtime fertilization is appropriate once the lawn is actively growing, about six weeks after the last frost date.
- Using slow-release fertilizer prevents nutrient overload and lowers the risk that your application will contribute to shoot, not root, growth.
When choosing a lawn mower, take into consideration the size of your lawn, the presence of inclines and obstructions, comfort (if you decide to go with a riding mower), safety and maintenance. You want a mower that will suit your unique landscape and be user-friendly. When you mow,
- Never cut more than one-third of the blade; any more will shock the plant.
- Cut your lawn higher than the recommended rate during hot summer months.
- Switch mowing directions to prevent turf wear and soil compaction.
