Lawn watering and fertilizing techniques

A lush, green lawn is a sight to behold. Many variables are involved in growing and maintaining grass, and water and fertilizer are among the most important components.

Knowing how much water and fertilizer to apply and when to apply it can make a big difference in the appearance and health of a lawn. That’s because a well-fed and watered lawn will develop a better root system, which makes the lawn less vulnerable to stressors like drought, mowing, foot traffic, and heat, according to the Scotts® company.


There is no magic formula governing when to fertilize a lawn. The type of grass and how well-established a lawn is must be considered. Experts suggest having the soil tested to determine its pH levels and if any nutrients are lacking. A fertilizing schedule can then be developed after testing.

Keep in mind that overfeeding a lawn will not make it grow any better and actually can damage the turf. Several small applications of fertilizer during the lawn’s most active growing period may be helpful, advises the home improvement resource Tools Around the House. An annual application (late spring for warm-season grass or fall for cool-season grass) may be all that’s needed.

Certain fertilizers need to be applied and watered in. Others may be combined with weed-control products and must be set on top of damp grass. Read packaging to determine the right application.


The right watering schedule and techniques can help a lawn thrive. Scotts® says adjusting for climate and nature can help grass to grow strongly. A lawn that has a grayish cast or appears dull green is telling an owner that it needs water. Another test is to step on the lawn. If footprints disappear quickly, the grass blades have enough moisture to spring back.

Water the lawn in the morning before 10 a.m. when it’s cooler and the winds tend to be calm so that the water can soak in. For those who must water at night, do so in early evening so that the water can dry before nightfall and will not contribute to disease.

Scotts® says to water an established lawn until the top six to eight inches of soil is wet. Most lawns need one to 1.5 inches of water per week from rain or a hose to soak the soil that deeply.

Newly established lawns may require more water to keep the soil moist but not soggy.
