Mow the yard regularly to strengthen the roots.
Mow in different directions each time you mow. Prevent the grass from lying flat by mowing in different directions.
Mow with a sharp blade. Take the blade or the mower to a repair shop and have the blade sharpened periodically so the blade cuts the grass rather than tearing it.
Cut only the top one-third of the blade of grass when mowing. Avoid shocking the lawn by cutting it too short. Use a mulching mower and leave the mulch on the lawn; the clippings degrade and feed the lawn.
Water the lawn in early morning or late evening to prevent evaporation.
Water the lawn for an hour or two once a week to achieve deep watering and stronger roots. Increase the number of waterings in extreme heat or drought.
Use drip irrigation hoses or sprinklers that keep the water close to the ground for more effective watering.
Fertilize the lawn with a high-quality time-release fertilizer in the spring.
Fertilize with a high-quality fertilizer plus weed controller in mid-May to prevent crabgrass and other weeds from choking out the grass.
Use a fertilizer with bug control in mid to late summer to prevent damage causing pest infestations.
Overseed your lawn every fall. Overseeding is applying seed to the lawn with a spreader in one direction and then reseeding the lawn with a spreader in the other direction.
