Mowing your lawn properly will help keep your lawn healthy and attractive. Proper maintenance such as cutting at the right height and watering correctly will create less maintenance for you in the long run. Keep in mind that along with proper mowing, your lawn will need at least one inch of water per week or the equivalent of using a sprinkler for one hour.
To keep your lawn at its best, most lawns should be cut to three inches in height in the summer, and no shorter than two inches when the temperature is cooler. Cutting too short will cause your lawn to lose too much moisture, forcing you to water more often. Too much exposure to the sun can cause weak growth and your grass could turn brown and die. Cutting your lawn taller will not only help your lawn look its best, but allows the grass roots to grow deeper and be more resistant to drought. Roots and soil will be more shaded because of the growth, helping to keep weeds at bay. Lawns should be cut at no lower than two inches during cooler temperatures. Never cut more than one third of the length in one mowing and do not mow while the grass is wet.
Avoid cutting your grass when it is wet. Not only can it clog and cause damage to your mower, but it can help fungi and bacteria to spread around your lawn and cause clumps and uneven cutting. The only time it is advisable to cut your grass while wet is if it has grown too tall and you have no choice, such as during extended periods of rain. Just avoid cutting more than one third of the grass by raising the blades to the appropriate height. If you must cut wet grass, do it with sharp mower blades. You can break up the job among two days if you need, to avoid cutting too much off at once. Do not bag wet grass clippings as this wet grass can become too heavy and you can injure yourself.
Frequency of Cutting
Waiting too long to mow your grass can cause your lawn to become stressed. Any time more than a third of the grass plant is removed at once the plant must use its stored energy to regrow the lost surface instead of producing and storing food. Keep an eye on the weather and the height of your grass to determine when the mow.
