The term "lilac lawn" does not mean a lawn covered with fragrant, blooming lilac shrubs. "Lilac" is an acronym for "Low Input Lawn Care." Lilac lawns differ from other lawns in that they are cared for naturally. Lilac lawn keepers do not use expensive, high-powered fertilizers or chemicals, nor do they provide the lawn with constant upkeep. Lilac lawns simply require water and general mowing, and are allowed to grow naturally. Lilac lawns grow best in areas that receive little traffic and are not affected by pests and insect infestations.
Check your lawn to determine if it can be kept as a lilac lawn. Ensure there are no insect or pest infestations and that the lawn will not receive heavy traffic on a daily basis. If there are signs of infestations, simply treat them using an organic insecticide/pesticide from your local garden specialty store.
Plant a low-maintenance grass seed on your lawn. You can ask a gardening professional at your local garden specialty store or plant nursery to show you which grass seed is needed for your lawn. Low-maintenance grass will grow slower and more easily than other types of grass.
Water the lawn weekly or as needed to keep the lawns soil moist to the touch, but not soaked. Installing a sprinkler system in your lawn can be beneficial; however, watering your lawn with a water hose and shower nozzle will do just as well. Lilac lawns live on 1-and-½ inches of water per week. During a drought, watering the lawn more often will be necessary.
Allow the grass to reach a height of 4 inches, then mow the lawn, cutting the grass down to a height of 2-and-½ inches. Do not mow the lawn again until the grass reaches a height of 4 inches.
Fertilize the lawn once per year during the month of September using an organic fertilizer. Do not use standard fertilizers to fertilize the lawn. Using organic fertilizer will thoroughly fertilize your lawn without harming the environment with harsh chemicals.
