Green grass instantly spruces up any landscape. It is normal, however, for grass to lose some of its vigor over time. The growth slows down and your lawn may start to look sparse. There are several ways to get grass green. Good care practices such as watering, fertilizing and mowing can help. You can also overseed the grass, which entails planting the same variety of grass seed over the existing lawn to make it thicker.
Water your grass slowly and deeply. Some homeowners water their lawn often, but they don't do it long enough to really penetrate the soil. One inch of water will go half an inch into the soil. Let the sprinkler run long enough to moisten the soil adequately. Use the touch test to determine when the moisture is deep enough.
Water grass in the morning to make it green and prevent pest infestation. If you water it early enough, the sunshine will dry out most of the moisture before nightfall. Watering it at night, however, will keep it moist for too long, inviting diseases and pests.
Mow the lawn to keep it between 2 and 3 inches tall. Cutting it too short will cause it stress and increase the likelihood of browning. Don't cut off more than one-third of the grass height at one time.
Fertilize grass in the late summer to early fall in the north and mid-spring in the south. Use a blend with a high amount of nitrogen, which promotes thick growth and a vibrant green color. Nitrogen will also give the grass the strength to combat pests, diseases and weeds.
Use a slow-release or water-insoluble type of fertilizer. They last much longer and do not require frequent application. Many brands contain both fast- and slow-release nitrogen. Choose one with most of the nitrogen in slow-release form.
Cut the grass as short as possible to create a 1-inch stubble. Set your mower to the lowest wheel height. This will give the grass seed soil to adhere to.
Loosen the soil with a metal rake. Grass seed needs air pockets in the ground for root spread and growth. Remove all debris except for the stubble.
Apply a starter fertilizer that contains a lot of phosphorus. Spread seed over the existing grass with a mechanical spreader. Make sure to apply an even amount so that the lawn is uniformly green.
Water the newly planted seed daily to keep it consistently moist. Do this until the seed sprouts.
