Pick a type of grass that is suitable for your specific climate and location. The right kind of grass for your environment will be able to naturally adapt to any climate changes the year may bring. Ask at a local nursery or hardware store for grass best suited for your location.
Get rid of existing weeds. Weeds take nutrients from the soil that grass needs to grow properly. Pull the weeds manually, or purchase a lawn-safe weed killer to remove them from your yard.
Fertilize the grass properly. Add the specified amount of fertilizer to your lawn, following manufacturer's directions. Do not add more than the recommended amount, since this can negatively affect the grass growth.
Add moisture to your lawn by watering your grass on a daily basis, starting in the spring. Reduce watering during the remainder of the spring and summer.
Mow your grass at the proper height. Cutting the grass too short will resort in damage to the grass and allow for more weed growth.
Spread your grass cuttings over your lawn evenly. The cuttings will act as a natural fertilizer, since they contain nutrients as they decompose.
