With some preparation, you can have an attractive lush green lawn, as well as rid your lawn of brown and bare spots. It is important to understand what type of lawn you have: grass, climate, region or soil, and buy fertilizers and weed controls accordingly.
Make sure the soil is not too compact. An easy way to assure this is to till your grass to provide loose soil. This helps the water get to the roots more easily.
Test how you water your lawn. Keep in mind that it is better to water deep into the roots, about 1 to 2 times per week. After watering for about 15 minutes, take a small trowel and dig into the soil to see if the water has penetrated about 4 to 5 inches deep. If it hasn't, then water for another 10 minutes, or rent a lawn aerator to help make the soil less compact. Try to water the lawn in the morning so that the water can dry out during the day.
Find your fertilizers according to your type of grass, climate and size of your lawn. Make sure to read the label to see the dose instructions. Too much fertilizer will kill your lawn, but too little will be ineffective. For ultimate efficiency, use a fertilizer spread that will apply it evenly. Fertilize in the spring and then at the beginning of the fall.
Make sure your lawn mower blades and very sharp, and maintain them regularly. Mow your lawn once a week, keeping the grass at a reasonable length. Never remove more than 1/3 of the blade.
Keep a close eye on your grass to make sure pests or weeds are not an issue. If you discover an infestation or weed problem, visit a local nursery to find a solution to your problem.
