Green grass is healthy grass. Maintaining healthy, green lawn grass requires creating optimum environmental conditions. Lawn grasses come in a wide variety of species, but most prefer moist, nutrient-rich soil and partial to full sunlight. Lawn grass will become brown and sparse in inadequate environmental conditions.
Regular watering of lawn grass will promote grass growth. Watering the lawn is best accomplished during the morning because of the cooler temperatures and calmer winds. Most lawn grass species will benefit from an average of 1 inch of water per week during the summer months.
Most lawn grasses benefit from annual fertilizer applications during the early spring and late fall. Fertilizer provides moisture retention, temperature moderation and minerals and nutrients to the top soil. During the summer months, lawn grasses will be sufficiently fertilized by the lawn clippings after mowing. Overfertilization can result in thatch buildup and weed growth.
Trim back adjacent trees, branches and bushes to maximize the amount of sunlight reaching your lawn. Sunlight provides the energy for grass growth, and most lawn grass species prefer full, direct sunlight. Shady lawn environments stunt the growth of grass and provide opportunities for weeds.
Lawn grass height is a direct reflection of root system depth, which makes lawn mowing much more important than the obvious aesthetic value. Most lawn grass species should be cut regularly to a height of 2 to 3 inches. Lawn mower blades should be kept sharp to provide a clean cut.
