Growing a healthy, green lawn requires consistent maintenance and attention. Though regular maintenance is required, it does not have to be a strenuous and tedious chore. In fact, when lawns are cared for on a regular basis, a simple mowing and watering will usually bring about great results.
Irrigate the grass thoroughly, allowing the water to reach the roots. Water the lawn in the early morning, providing at least one to two inches of water before the height of the afternoon sun. This will allow the root system to absorb the water before it is evaporated by the sun's heat.
Develop a watering schedule that meets the needs of the grass, usually once a week. Increase the watering schedule during the hot, dry summer months. Always reduce the schedule for extensive rainfall. Promote a dense lawn by allowing the lawn to dry in between watering.
Mow the lawn regularly as it grows, especially during the rapidly growing summer months. Ensure that the mower's blades are sharp to avoid jagged cuts. Clean the blades of the mower before or after each mowing to ensure that undesired seeds and disease are not distributed throughout the lawn. Cut the lawn so that at least one-third inch of the grass blade remains.
Fertilize the grass two to four times per year to promote lush growth. Feed the grass during the growing season beginning in early spring. Apply every four to six weeks until the fall. Select a well balanced, slow release fertilizer that contains nitrogen, phosphorous, and potassium. Distribute the fertilizer evenly and use according to the directions. Avoid over fertilizing to prevent blade burn.
Remove weeds and crabgrass immediately to prevent spreading. Pull weeds by hand from their location; being sure to remove the root as well. Discard the weeds immediately to prevent the spreading of seeds. Prevent weeds and crabgrass by treating the lawn with a pre-emergence herbicide during the early spring.
Remove debris, cut grass, and matter such as stems, branches, and plant leftovers from the grass. Complete this process regularly, especially after mowing, to help control thatch. Controlling thatch will help reduce the potential for disease and increase the moist and nutrients that reach the root system.
Inspect the grass regularly for signs of infestation and disease. Look for dying, browning, and yellowing spots or areas in the lawn. Treat any infestations or disease immediately. Spray the lawn once or twice annually with an insecticide to eliminate and prevent infestation. Speak with a lawn specialist for disease diagnosis and treatment selection assistance.
