Prevent Lawn Disease

Stop Them before They Start

When it comes to dealing with lawn diseases, the old saying holds true: “an ounce of prevention is worth a pound of cure.” It’s easier to prevent lawn diseases than to cure them. Following these basic guidelines for a strong lawn will help you protect your lawn from fungal diseases.

Feed Your Lawn Regularly

Nutrient deficiencies can weaken grass plants, so feed at least 2 times per year to keep your lawn strong and vigorous. If your lawn is used often for activities involving kids, pets and parties, feed 3-4 times per year. A nourished lawn is better able to fend off diseases.

If You Need To Water, Water Properly

Many diseases infect lawns when the grass blades are wet. To keep grass blades dry, water only if needed and water deeply so you can go longer between watering. Watering in the morning, between 6AM and 10AM, is best since the grass blades have plenty of time to dry during the day. Especially avoid watering late in the day or at night, since the grass blades will stay wet all night long, encouraging leaf diseases.

Mow Regularly at the Right Height

Mowing too short weakens the grass plant, making it more susceptible to infection. Most grass types should be mowed using a high (3-4 inch) mowing setting. Mow often enough so that no more than 1/3 the height of the grass blade is removed at one time.
