The lawn should be mowed at least once per week. It is almost always true that the greenest, healthiest most weed-free lawns are the ones which are regularly maintained at a height of 3-4”. ALWAYS use a sharp blade. A dull mower blade rips and shreds the tissues of the grass blade, causing them to become brown. A rapid escape of internal moisture from a torn blade allows fungal spores to easily enter the wounds, which leads to disease. If you are mowing in early morning, it is beneficial to water immediately after, allowing the grass plant to recover from the stress of being cut. With weekly mowing, it is recommended that you leave the clippings down to provide further nutrients to the lawn. Remove the clippings if the grass is allowed to grow to a height beyond 4” or if there are clumps remaining.
