Get to the root of a dry lawn

Weather can be unpredictable, even during the warmest months of the year. Summer days may feature strong thunderstorms and downpours, followed by stretches of extremely hot and dry conditions. Weather extremes can take a toll on lawns, especially when drought is part of the equation. The results can be anything from dry patches to a scorched landscape, leaving homeowners wondering what they can do to repair the damage.

According to The Spruce, dry grass can happen in as little as a week without adequate care and water. Sometimes dry grass can be the result of disease, pets, or pests. A healthy lawn will be lush and green; a dry lawn quite the opposite. It's crunchy, uncomfortable and muted in color. Here's how to address a dry lawn to restore it to it's natural beauty.

Pet urine

Animal urine often is the culprit behind dry patches in a lawn. Lawns need nitrogen to grow, which is why it is included in many fertilizers. But the nitrogen in dog urine is concentrated and directed in one area, so much so that it chemically burns the lawn. This concentrated nitrogen causes the grass to dry out, turn yellow and eventually go brown and die.

Rinsing areas where dogs urinate on the lawn or creating a separate potty area in the yard can help alleviate brown spots.

Lawn height

Sometimes a lawn mower might be to blame for a brown lawn. According to Scotts®, the higher a person mows, the deeper the lawn's roots will grow. That can help the lawn thrive under restricted water conditions and insulate the lawn from some of the effects of hot, dry weather. Never remove more than one-third of the total height in a single mowing, as that can stress the lawn.

Diseases

Leaf blight, brown patches and powdery mildew are just some of the diseases that can affect a lawn. Fungal bacteria can spread on a lawn and contribute to these conditions, which makes it important to aerate and dethatch the lawn in cooler seasons to help prevent disease.

Improper pH

A lawn requires a certain pH to grow well. According to Weed Man Lawn Care Services, the ideal pH range for lawn soil is between 6.0 and 7.0. Anything outside of this range may result in poor, brown grass. A soil pH test will indicate if the soil is acidic, alkaline or optimal. Amend an acidic soil with lime and an alkaline soil with sulfur in small amounts until a balance is reached.

Pest infestation

People are not the only creatures that like a lawn. Many pests feed on blades of grass or the roots. The result can be patchy, dry grass. Figuring out what is causing any damage is essential. Homeowners can then take steps to remove the pests and return the lawn to its former glory.

Dehydration

Deep watering can help restore a lawn that has widespread wilting and browning. Popular Mechanics advises homeowners begin watering more in spring. Water infrequently but for longer periods of time to encourage roots to deepen. The ideal time to water is between 5 a.m. and 9 a.m. to limit evaporation.

Trial and error may be necessary to figure out why a lawn is brown and what's needed to revive it.
