How Can I Help Grass Grow?


Grass is often difficult to grow. Sometimes homeowners are plagued with patchy, weedy and yellow grass. Fortunately, with some changes and good care techniques you can finally begin to get your grass to grow and grow green. First though, you must find out what kind of grass you have. Look on the back of the seed bag if you still have it, or take a sample to your local nursery or local county extension office. Knowing what kind of grass you have will point you in the right direction on how to help it grow.

Step 1

Mulch over a newly seeded lawn with straw. Apply it so you can still see 50 percent of the soil. Straw helps the soil retain water so you don't have to water it as frequently. Keep your soil bed moist until the grass grows to a height of 2 inches. The soil should not be soggy. Respread the straw if it blows in the wind, as necessary.

Step 2

Mow the grass to a proper height. Most homeowners may cut their grass too short, which only increase weeds that take valuable nutrients and water from the grass. Most grasses should be mowed at a height of 2 to 3 inches; however, some grasses, such as Bermuda grass, are best mowed shorter than this. In general, bunch-type grasses are mowed higher than creeping or erect grasses.

Step 3

Water your grass properly in the morning or late evening. Deep rooted grasses, such as buffalo grass, don't need as much water as shallow rooted grasses, such as bluegrass. In addition, grass growing in the shade needs less water than grass growing in the sun. Typically though, grass needs about a 1/2 to 1 inch of water per week during the growing season (when it's green), but some grasses need more, especially during the hot summer months or grass growing in clay soil.

Step 4

Fertilize your grass to help it grow. Different grasses have different fertilization needs, but in general, most grasses need a fertilizer high in nitrogen and should be fertilized three times a year in the early spring, late summer and midfall (two to three weeks before the ground begins to freeze). Do not fertilize your grass too much--always read the label carefully before applying.

Step 5

Keep the weeds out of your lawn. Remember mowing your grass higher will help keep the weeds out. You can also apply a weed herbicide but always choose one safe for your grass and follow the label instructions. Also, pull the weeds out with either your hands or a weeding tool. Insert the prong end of your weeding tool into the soil, dig under the weeds and pull up. Weeds are easier pulled when the soil is wet.
