How to Make Brown Grass Green

Overview

Green lawns create a finishing touch in many landscape designs. These stretches of living carpet enhance the beauty of a yard, as well as create a functional area for activities involving pets and people. Because lawns are made up of numerous, individual grass plants, these areas of the landscape often suffer from various diseases and conditions that turn healthy grass brown.

Step 1

Look closely at your lawn to determine the cause of brown grass. Determine whether the tops of the blades of grass show signs of damage or if entire areas suffer from this change in color. If you notice browning only near the tips of the grass, check your lawn mower blade. Dull mower blades create jagged tears in the tips of grass, creating small wounds that shrivel and turn brown. In this case, sharpen your lawn mower blades.

Step 2

Look for thinning grass among the areas of brown patches. One particular type of fungus, known as brown patch disease, causes circular patches of brown grass in affected areas. Examine an individual blade of grass for the appearance of dark brown margins and tan spots along the length of the blade. This indicates the presence of a brown patch.

Step 3

Water your lawn in the early morning to eliminate brown patch disease. Allow the natural light and heat of the day to evaporate excess moisture. This type of mildew thrives in lawns that remain moist during warm seasons. Avoid watering in the late afternoon and evening when moisture does not have a chance to evaporate.

Step 4

Avoid using fertilizers high in nitrogen. Nitrogen fertilizers increase the presence of fungus found in brown patch disease. Don't make the mistake of treating brown grass with fertilizers containing nitrogen. This usually exacerbates the problem.

Step 5

Apply a fungicide to brown patches of grass. Purchase a fungicide formulated for use on your type of lawn grass. Apply the fungicide on a calm day to avoid uneven distribution due to windy conditions. Follow the manufacturer's instructions when applying fungicide.

Tips and Warnings

  • Avoid cutting the grass to a length shorter than 1 inch. Very short trimming damages grass blades and increases the possibility of disease.
