Find out the ideal mowing height for your grass type. We'll tell you how high to set your mower and how often to cut for a healthier, better-looking lawn.
Mowing height directly affects root depth, drought tolerance, and overall lawn health. Taller grass develops deeper roots and better stress resistance, while shorter grass requires more frequent mowing and watering. Each grass type has an optimal height that maximizes its natural characteristics.
Mowing frequency varies by grass type and season. Cool-season grasses typically need weekly mowing during peak growth (spring/fall), while warm-season grasses may need mowing every 3-5 days in summer. During dormant periods, mow only when necessary. Never remove more than 1/3 of the grass blade at once.
Yes! For cool-season grasses, raise height during summer stress (3.5-4 inches) and lower gradually in fall for winter preparation. Warm-season grasses should be mowed at optimal height during growing season and allowed to grow taller before dormancy. This helps protect roots and improve stress tolerance.
Mowing too short (scalping) can stress grass, reduce root depth, increase disease susceptibility, and create bare spots. It also makes grass more vulnerable to drought, heat stress, and weed invasion. Always stay within the recommended height range for your grass type.
Mulching (leaving clippings on the lawn) is generally better for lawn health. Clippings return valuable nutrients (especially nitrogen) to the soil, reduce fertilizer needs, and help retain moisture. Only bag clippings if they're excessive, wet, or if you're treating for disease.
