Why biweekly isn't always cheaper
Biweekly looks like half the price, but each cut takes longer when grass is taller, and many companies charge more per visit for it. In peak spring growth, two weeks of growth can mean cutting off much more than a third of the blade at once. That stresses the grass, leaves clumps, and can scalp thin spots.
The one-third rule
Never remove more than a third of the grass blade in one cut. If you mow at 3 inches, the grass shouldn't get much past 4.5 inches between visits. On Long Island in May and June, that usually means once a week.
A mowing calendar for Long Island
- April: first cuts as growth starts.
- May to June: weekly. Peak growth.
- July to August: weekly or biweekly, depending on rain and irrigation.
- September to October: growth picks up again, especially on overseeded lawns.
- November: final cuts with the fall cleanup.
Mowing height and clippings
Suffolk County's lawn guide recommends mowing 3 inches or taller so roots grow deeper, and leaving clippings on the lawn to return nutrients to the soil and reduce fertilizer needs. Taller grass also shades out crabgrass and holds moisture in Long Island's sandy soil.
Sharp blades matter
A dull mower blade tears grass instead of cutting it, which leaves ragged, brown tips and makes the lawn more prone to disease. If the tips of your grass look shredded or white a day after mowing, the blade needs sharpening.
Change your mowing pattern
Mowing in the same direction every time can compact wheel tracks and make grass lean. Alternating direction from visit to visit keeps the cut even and the lawn standing upright.
Mowing in summer heat and drought
- Keep the height up. Taller grass shades the soil and holds moisture.
- Skip a cut if the lawn has stopped growing in a dry spell.
- Avoid mowing in the hottest part of the day when the lawn is stressed.
- Water about 1 inch per week including rain, which is Suffolk County's guideline.
What a full mowing visit usually includes
A professional mowing visit typically includes mowing, string trimming around beds and obstacles, edging along walks and driveways, and blowing clippings off hard surfaces. Bagging and haul-away is usually an add-on, since clippings left on the lawn are better for it.
