Lawns are meant to provide a beautiful, comfortable outdoor space for families to enjoy, but who wants to relax on dead, dry grass? If your lawn is turning yellow, you may find yourself at a loss to reverse the damage. Increasing your watering doesn't always work, which is when it's time to turn to the experts. These are five ways to restore your lawn to its former glory and keep it green year-round.
Finding the Right Fertilizer Balance
Fertilizer gives plants the nutrients they might not get from the soil, but it can also do more harm than good. The nitrogen in fertilizer is a necessary element for life, but it can burn plants in high concentrations. Many homeowners notice their grass yellowing, apply more fertilizing, and actually make the problem worse. A professional lawn care company should be able to run a soil test on your lawn and correct any chemical imbalances without going overboard.
Eliminating Pests and Disease
In other cases, a brown lawn is the result of pests and disease. When paired with other stressors, an insect infestation can be enough to push your lawn to turn yellow and dry out. Lawn diseases like yellow patch are common in bluegrass and fescue turf. Yellow patch is encouraged by too much nitrogen in the soil, so avoid over-fertilizing to prevent it. Most lawn diseases can be treated chemically, but it is often faster and more effective to simply replace the effected turf.
One frequent cause of yellowing grass is acidic soil. This typically occurs in areas with evergreen trees or shrubs, which drop their acidic needles to the ground below to leech into the soil. You may notice that your lawn becomes increasingly brown and patchy under these trees, spreading to the rest of the grass over time. If the trees need to stay, there are steps you can take to balance your soil's pH to counteract their acidity. Talk to your lawn care service to test the soil and begin making amendments.
Letting the Grass Grow Longer
It can be tempting to mow your grass as short as possible to give yourself more time between mowing, but doing so may hurt your lawn. Grass blades rely on their leaves to provide enough surface area for photosynthesis, and those leaves also hold energy reserves for when the grass is stressed. Cutting off too many of those leaves at a time not only stresses the grass, but it also removes its ability to cope with the loss. Trim your grass to about 3 inches in length per mowing to keep it healthy, functional, and a vibrant shade of green. Talk to a professional like Valley Green Companies for more information.
