A homeowner's dream is a healthy, emerald-colored, thickly-grown yard all season long, but this is quite a challenge to achieve--especially in certain climates. Aside from the basics of lawn care, additional care is necessary to make your grass as thick and lush as it can be. This includes mowing regularly at the highest setting, establishing a watering cycle and fertilizing consistently.
Mow the lawn when it is dry once a week in spring and summer, and twice a month in fall and winter. Use the highest setting on the grass to help the soil retain moisture and nutrients. This will help it become disease resistant and deter weed growth.
Water young grass deeply once a week either first thing in the morning or in late afternoon to help establish deep roots. For mature lawns, water about 1/2 to 1 inch per week depending on your rainfall and climate. A good rule of thumb is to water once the grass blades start to curl.
Use a mulching mower if possible to provide nutrients back into the soil from the grass clippings. Not only do the clippings protect the grass and roots, they help retain moisture as well.
Obtain a pH test (available at local gardening stores) to test several sites on your lawn. This will help you understand exactly what type of nutrients the soil needs. Test the soil each spring and fall.
Fertilize the lawn four times a year, starting in the spring season when the grass starts to grow. Every three months thereafter, fertilize again until late fall. This will help encourage fast growth in spring, deter weeds, strengthen the root system and keep the grass a beautiful emerald hue.
