If you mow your lawn, but are not doing it correctly or routinely, then you may be contributing to the turf's ultimate demise. Routine, precise mowing techniques help your lawn thrive and without them, your grass can weaken, which in turn makes it much more susceptible to the threats of fungal lawn disease or harmful insect invasions.

At Sprout Lawn & Landscape, our lawn mowing experts have determined the ideal mowing heights for each type of cool-season grass that we have in Noblesville, Westfield, Carmel, and nearby areas of Indiana. Learn about how you should mow Kentucky bluegrass, perennial ryegrass, tall fescue, and fine fescue.

Kentucky bluegrass should be kept at certain heights in spring, summer, and fall.

If your lawn is made up of Kentucky bluegrass, then it needs to be kept at certain heights during the growing season. In spring and fall, make sure the grass blades are around 2.5 to 3 inches in height, while the summer height should be an inch taller at 3 to 3.5 inches.

The difference in height can be attributed to the fact that cool-season grasses grow faster in spring and fall, whereas the growth slows somewhat in the summer.

Your perennial ryegrass needs to be about 2 to 2.5 inches in height.

When mowing perennial ryegrass, you need to make sure the grass is about 2 to 2.5 inches in height. This keeps it from getting too short. In summer, consider adding a half inch in height so that the grass will be just tall enough to shield the soil and prevent it from being dried out or scorched. This type of grass does also enter dormancy in hot weather, so the grass may appear brown, but the added length in summer allows the blades to still perform photosynthesis.

Keep tall fescue grass at a height of 3 to 3.5 inches.

Tall fescue is a very strong and disease-resistant grass, but only when it is properly cared for and mowed. To ensure this type of grass is at its peak, we recommend keeping it at a height of 3 to 3.5 inches. Especially during the summer, never mow this grass too short. The soil can lose too much moisture and the lawn itself may begin to thin out, leaving it open to weed invasion.

The recommended height for fine fescue is 3 to 4 inches.

Since fine fescue stays green all year and is very drought tolerant, it is often a popular choice in Indiana. Our recommended mowing height for this grass is about 3 to 4 inches. Keeping this grass at a slightly taller height encourages a thicker lawn and allows for deeper root formation.
