For moderate, even development, use a total of 4 to 6 pounds of real nitrogen per 1,000 square feet of lawn area every year. Prevent using more than 1 pound of actual nitrogen per application.

Fertilizer needs to be used throughout the active growing season of the turf, which generally is throughout spring and summer for warm-season turfs and during fall and spring for cool-season lawns.

Keep sharp mower blades to prevent mechanical damage to turf. When grass is trimmed routinely, clippings can be left on the lawn, a practice called "grasscycling." Grasscycling hasn't been found to considerably increase thatch or disease incidence. For extra info, see Trimming Your Lawn and "Grasscycling" listed in Referrals. Soil compaction decreases root growth as well as recuperative ability, hence increasing a lawn's relative vulnerability to diseases.

Growing needs to be done throughout times when the yard is growing vigorously and can take benefit of the decrease in soil compaction (spring and succumb to cool-season grass and early summer season for warm-season yard). Thatch is a partially decomposed layer comprised of roots, stems, roots, crowns, and stolons above the soil surface area.

Keeping Kids Safe With Pest Control

Thatch layers greater than 1/2 inch need to be removed to prevent restricting water entry into the root zone. Several turfgrass pathogens can make it through in the thatch layer, including those that trigger summertime patch, leaf area, and melting-out diseases. Heavy thatch may also result in fairy ring problems. Bermudagrass, Kentucky bluegrass, and kikuyugrass produce more thatch than the majority of other turfgrasses and require routine dethatching.

Collect entire lawn plant samplesleaves, stems, roots, and soilfrom a number of yard areas that appear to display different stages of the observed symptoms.

Keep in mind that the pathogen isn't always active in the part of the turf plant exhibiting disease symptoms, so make certain to consist of the entire plant. Signs observed in the foliage such as chlorosis (yellowing) or wilting might be associated with a vascular wilt or a root rot.

Curing Fungal Lawn Quickly

It is more widespread in cool-season yards during durations of high humidity.
