For a great lawn, you need to spend some time maintaining it. Nutrients are needed for thick, green growth. The three things you need to do are water the grass, feed it and mow it regularly. Grass tends to lose nutrients and grow sparse after several years. Attention and care will keep your lawn in its best health.
Supplement your lawn with water if it is not raining enough. You'll know that the grass needs water if it's wilting or if footprints are still visible after walking on it. Apply 1 inch of water during a deep watering. This is better than watering in short bursts.
Keep grass at a height of 2 1/2 inches tall. Mowing grass too short will make the grass unhealthy. Let it remain taller. Do not mow more than one-third of the height at one time.
Make the grass green by feeding it with a fertilizer that contains a lot of nitrogen. Choose a product with a nitrogen-phosphorus-potassium ratio of 4:1:2 or 3:1:2.
Apply 1 lb. of nitrogen per 1,000 square foot of lawn during each feeding. Over the course of a year, apply a total of 3 lbs. of nitrogen.
Fertilize warm season grasses such as bermuda grass and zoysia in the summer. A time-release formula is the easiest and has the best results because it continuously feeds the grass over a period of time.
Fertilize cool season grasses such as fescue, bluegrass and ryegrass at the beginning of fall. Apply fertilizer again in the middle of spring to get good growth and thicker foliage.
Read the fertilizer bag to determine how much to apply to your lawn. Fill a broadcast spreader with the right amount of food and spread it evenly over the grass.
Water grass after fertilizing it. This helps wash the nutrients down into the ground, to the roots. Water in the morning before it gets too warm outside.
