The Grass Cutting Dilemma
There many aspects to trimming your lawn, such as trimming, watering, seeding, and fertilizing. Two of the most common questions that get asked about grass height and frequency to cut.
- How high to cut grass?
- When you mow your grass?
How High To Cut Grass?
A general rule of thumb for determining grass height, and in fall it’s generally easy to stick to that rule of thumb. An optimal height for a cool-season grass in fall is about 2 1/2 inches. And at each mowing, you should only be removing about the top 1/3 of the grass blade. Consequently, a good time to mow lawns is when your grass is about 3 2/3 inches high.
Why is 2 1/2 inches an optimal grass height? Well, what you’re striving for is a balance. On the one hand, mowing the grass is like “pinching” a garden plant to stimulate rugged growth. So if you’re letting the grass get tall, you’re not mowing very much, which means you’re passing up opportunities to make your lawn healthier and more attractive. But if you cut grass too short, it can become stressed.
When to mow your grass?
The height the grass has attained that should determine when it’s time to mow. It would be inconsistent to establish a schedule for mowing based on length of time between mowing’s. For instance, advising someone to “mow every other week” fails to take into account the growing conditions during that period of time. Rainfall stimulates growth in lawns, so the presence or absence of rain will have a great impact on mowing frequency.
While the 2 1/2-inch height for a cool-season grass is optimal for the fall, it is hardly an absolute figure that must be adhered to throughout the mowing season. If you have a crabgrass problem, for instance, you may wish to make an adjustment in spring and summer. During these seasons that crabgrass, an annual weed, competes for space with your lawn grass. Some experts recommend keeping lawn grass around 3 inches tall during spring and summer. The extra shading that results may inhibit crabgrass enough to keep it in check. In fall, you can go back to maintaining the 2 1/2-inch height, since, by then, frost will have killed the tender crabgrass.
When your grass is dormant, you do not need to water. Which means not at all in most areas in the winter. When winter has passed and spring is on the verge, you can call on Prosper Sod to schedule your Spring Clean Up and Lawn Maintenance.
