Once conditions like Brown Patch Disease take root, you might notice thinned-out brown grass in a ring-like pattern, possibly affecting a large area of turf. Fight the threat of fungus.įungus thrives in hot, humid, moisture-rich environments, and stagnant water on your lawn helps it fester. Follow up weed removal by spraying pre-emergent herbicide over the lawn to prevent new weed seeds from sprouting. To treat, dig up the weeds or spray the lawn with a selective herbicide that targets weeds but leaves the grass undamaged. Weeds and tree roots siphon vital nutrients from fertilizer and water that would otherwise go to grass, leaving you with a dry brown lawn. As a long-term solution, reduce the frequency with which you water the lawn, as over-watering reduces iron uptake in grass and can lead to repeat cases of yellowing or browning. Sandy soil with a starting pH of 7.5, for example, only needs 10 to 15 pounds of sulfur per 1,000 square feet to reach an optimal soil pH of 6.5, while a loamy soil of the same pH needs 20 to 25 pounds of sulfur per 1,000 square feet. Generally, the higher the starting soil pH and the “loamier” or more clay-based the soil, the more sulfur it needs. If the pH is higher than 7.2, apply sulfur to your lawn as a short-term solution for lowering soil pH and improving the color of grass. Check your soil pH is with a home soil testing pH kit available at your local home center or nursery for about $10 ( view example on Amazon). When soil pH is too “alkaline” or acidic, iron chlorosis, a type of iron deficiency affecting plants, can take root in your lawn and lead to yellow-or in severe cases, brown-patches. Remember to water early in the day, before the sun’s heat burns off the water. You may need to adjust a sprinkler head to ensure that there are no spots on the lawn that the sprinkler isn’t reaching. You can also restore your lawn by giving it an inch of water on a weekly basis with your lawn sprinkler. It’s natural for grass to go dormant to conserve water during periods of limited rainfall, and drought-induced brown grass should turn green on its own as the weather cools and rainfall increases. If brown grass appears or worsens with scorching temperatures, and fallen tree leaves on the surrounding lawn have shriveled, this can be a sign that the problem is drought.
