-It may seem smart to water in the evening, especially if you have a sprinkler system because electrical rates are lower, however, without sun to evaporate it, water is more likely to cling to grass at night which promotes fungus.
Instead - water in the morning when the air is cool, the sun is arriving, and there’s less wind than midday.
-Also grass blades collect sunlight. Cut them too short and they can’t soak up enough to survive, which makes for brown, patchy grass and weeds galore, and that means you just killed your home's curb appeal, too.
Instead - save the grass, and your home’s good looks, by cutting your lawn no more than one-third the length of the blades at each mowing. Overall, aim to keep the grass between two-and-a-half and three inches high.
