Everyone wants a thick, green, healthy lawn, and the key is regular care of your lawn and going the extra mile to provide adequate nutrients for the grass and soil. Evaluate the condition of your current lawn and take care of any problems, such as over- or under-watering and soil that is too compacted. Make sure to use products specific to your grass variety, region and climate.
If necessary, dethatch your lawn with the rental equipment. You will need to dethatch if you have a build-up of lawn debris or thatch more than 1/2 inch thick. Debris blocks sunlight and water from being absorbed into the roots. Simply rake your lawn if you have only a small amount of buildup, or after dethatching, to even out the soil.
Determine if you are watering too much or too little. The general rule is to water less and more deeply than constantly and too little. Depending on climate, deep water for 20 minutes once or twice a week. This encourages root growth, which deters weeds, and makes the grass more disease resistant, stronger and greener. After your normal watering, penetrate the soil a couple of inches to see if water seeped through. If not, adjust watering time.
Aerate your lawn if the soil is too compacted. Do this with aerating equipment rented from a local hardware or gardening store. Aerating your lawn will provide air circulation, water, nutrients and sun down to the roots.
Use a fertilizer in the spring and fall seasons. In the spring, fertilizer will help jumpstart the growth of the grass, making it fill in more quickly, thicker and greener. In the fall, fertilizer will protect the pH of the soil and keep the grass from turning yellow or brown. Use a fertilizer specific to your climate and lawn, following directions carefully.
Check with your local gardening store if pests or weeds are problems. Stores will have products specific to your region or grass variety that are effective.
Mow your lawn regularly using a mower with a sharp blade. Lawn care supplies that are not in top shape create a lawn that is not in top shape. Do not cut more than 1/3 of the blade.
