WATER AT RECOMMENDED AMOUNTS The lawn should receive 1-2" of water per week, either from rainfall, sprinklers, or both. Your lawn may need more water during the summer, when its moisture demand is at its highest. To determine how much water your lawn is receiving, place small cans under your sprinklers and measure the amount of water in them after a period of time, such as 1/4" after 1/2 hour. Therefore, you would need to water 1 hour for your lawn to receive 1/2" of water.
WATER AT RECOMMENDED TIMES The best time to water is early morning (4am-8am) when the wind is calm and less water is lost to evaporation. Watering in the late morning or evening will increase disease formation and severity. Watering every day develops shallow root systems and encourages weed growth. A good practice is to water 3 times a week, allowing the grass time to dry out between watering. Areas along curbs, sidewalks, and driveways dry out quickly, so they may need more water.
MOW AT RECOMMENDED HEIGHTS The best cutting height depends on the time of the year and your grass type. The lawn can be mowed shorter in the spring and fall, but should be mowed longer during the summer to help reduce stress. Areas with high traffic should also be mowed longer than normal. Bluegrass/Rye grass should be mowed 2.0-2.5" high in the spring/fall, and 3.0-3.5" during the summer. Turf type fescue should be mowed 2.5-3.0" in the spring/fall, and 3.0-3.5" during the summer.
MOW REGULARLY The lawn should be mowed weekly, and no more than 1/3 of the grass blade should be mowed off at one mowing. If you have a mulching mower, then the lawn should be mowed sooner to prevent excessive clippings. It is also recommended to alternate mowing directions. Mowing your grass in the same direction will cause tracks, matting, and streaking.
KEEP YOUR MOWER BLADE SHARP A dull mower blade will shred the tips of the grass blades causing them to turn brown, and it will also increase disease activity. Your mower blade should be sharpened every month, even if the mower is new.
