A lush, green lawn can serve both recreational and ornamental roles in your landscape, and can be something for which a homeowner can be very proud. Common lawn grass species, such as the popular Zoysia and Bermuda grasses, grow at varying rates. Whatever the type of grass you have in your lawn, you can practice lawn care techniques to encourage the grass to grow faster to create a healthy yard for your family.
Water your lawn thoroughly and deeply using a watering can, sprinkler system or garden hose. Deep watering sessions encourage the plants' roots to spread further, helping it to soak up extra hydration and soil nutrients to support proper development. Lawns should be watered at least once a week. Observe the lawn's health to gauge watering needs, as your climate may require more frequent watering sessions.
Fertilize the lawn once every three to four months. Fertilizer feeds the hungry grass and ensures sufficient nutrients for optimal growth rates. Use a standard liquid or granular lawn fertilizer available from all garden stores and nurseries. Apply according to the manufacturer's label, as nutritional potency varies.
Mow the lawn regularly with a riding lawn mower or a push lawn mower. Most grass species should be trimmed to a height of 1.5 to 2 inches; consult a nursery if you are unsure of your species' optimum height. Regular mowing immediately improves the appearance of your lawn and forces the plant to generate new grass blades, hastening the growing process. Keeping the grass low also helps the plant conserve energy that it can put toward spreading wider rather than growing taller.
Aerate your lawn every six months with a home aeration tool or by hiring the services of a professional lawn care provider. Aeration helps grass to grow faster by removing built-up thatch, improving the condition of the soil, encouraging healthy root development and boosting your lawn's ability to absorb soil and fertilizer nutrients.
Kill weeds in the grass, which may compete with the grass for space and nutrients and inhibit proper lawn development. Use a post-emergent broadleaf herbicide spray that is safe for your grass species but kills any present weeds. Alternatively, use a lawn fertilizer with pre-emergent herbicides to keep weed seeds in the ground from germinating.
