Proper lawn care requires feeding, watering, weeding and mowing, according to The Old Farmer's Almanac. If there are areas where the grass is thin or the soil is bare, the owner should also seed at the appropriate time to keep the lawn looking healthy.

As the grass comes to the end of its dormant period, it requires removal of thatch from the previous year. Aerating compacted soil ensures nutrients and water reach the roots of the individual plants. The Old Farmer's Almanac recommends spreading 1 to 2 inches of compost on the lawn and amending the soil with nitrogen fertilizer.

When it is time to water the grass, The Old Farmer's Almanac recommends evenings or mornings. It is important to provide enough water to penetrate the root zone before moving to another area. Flat cans, spread across the lawn, help to determine the amount of water that reaches the plants. Overwatering the lawn tends to attract insects and leach away important nutrients.

Homeowners should avoid mowing more than one-third of the length of the grass at any time. Mulching the clippings in place helps to maintain the soil, explains The Old Farmer's Almanac. Regular mowing helps to eliminate many of the weed problems associated with lawns; however, hand pulling the weeds is another important factor in keeping the grass weed-free.
