Stagnant grass is a common lawn care problem caused by a variety of issues ranging from improper planting to lack regular maintenance.
Light can be a major factor; the grass needs at least six hours per day, preferably in the morning. Soil pH should also be checked as it could be too acidic or alkaline for the grass species being grown.
Nutrition is another essential consideration; the right combination of nitrogen, phosphorus, and potassium should be applied according to the species in question. An unbalanced diet can severely limit growth, so soil tests are recommended.
Grass needs adequate water; humidity levels should be monitored to determine if irrigation is necessary, as dry conditions starve even healthy plants of vital moisture.
Mowing frequency is important; raising mower blades encourages healthy growth and reduces stress on grass plants that often experience drought or shade during summer months. Lastly, turf aeration can help revitalize stressed roots if overdone. However, this can further reduce available moisture, so caution must be taken before using this technique.
