Typically lawn fertilizers are used to provide lush and green lawns. Nitrogen is the main ingredient of these fertilizers. Some people do not wish to use fertilizers on their lawn. Without fertilizer, it is still possible to make your grass greener. In nature, supplemental fertilizer is not provided for plants and they are able to maintain their rich green color. Providing other care for your grass will be sufficient enough to keep it green and lush all year long.
Mow your lawn at a height of 2 1/2 to 3 1/2 inches tall every five to seven days. Mowing your grass high provides more surface area on each grass blade to photosynthesize. This enables your grass plant to become thicker and more lush.
Water your grass so it receives 1 inch of water per week. Apply this amount of water over one application. Deep watering encourages your grass roots to grow deep. Deep roots have better access to water during dry periods, which allows the grass plants to remain greener than shallower rooted plants.
Spread a 1/4-inch layer of compost over your lawn two to three times per year. Rake it in thoroughly so it falls down to soil level. Compost is rich in nutrients that will help keep your grass green.
Rent a dethatcher in the early fall and dethatch your lawn. Removing excessive thatch allows better water and nutrient penetration into the soil. It also allows more sunlight into your lawn and promotes a healthy lawn.
