When you're ready to give that first mowing in the spring, lower your mower height 1 or 2 notches so you're mowing your grass about 3 inches tall. Be careful not to scalp your lawn. This low mow will cut off the brown winter grass blades and open up the soil to the warm spring sunlight.
Early Spring – We recommend the first cut to be at 1.5” to 2” then raise the blade to the regular setting. 2.5” to 3” is the ideal mowing height for most grass types.
For this reason, some people prefer to mow at 3 or 3.5 inches. For the healthiest and most sustainable approach, Michigan State University Extension says 3.5 to 4 inches is most desirable. Lawns mowed at 3.5 or 4 inches out-compete weeds, tolerate grubs and look just as good as lawns mowed at 2.5 inches.
Mowing too soon, before the turf grass has begun to grow and thicken up, exposes the soil and over-wintering weed seeds to sunlight. Warmed by the sun, weeds germinate and grow rapidly, invading otherwise weed-free turf and resulting in a what can be a weed control problem for months.
Remember the mowing “rule of thumb”. For optimum turf health “try not to remove more than 1/3 of the leaf blade during any one single mowing”. For example, this means that for a lawn being maintained at 3 inches you should not be removing more than 1.5 inches of leaf tissue or mow when the turf reaches 4.5 inches.
We recommend performing bi-weekly lawn maintenance in March. We have found that this schedule encourages growth in most yards. Furthermore, we recommend that your first mow be a “mow low and bag.” You can mulch your grass at almost every mowing service for the season, but the first one really should be bagged.
'If your lawn is in good condition and has been properly cared for throughout the fall and winter, it should be ready for mowing by late March or early April,' says Stacie Krljanovic. 'However, if your lawn is in poor condition, it may need some extra care and attention before you start mowing.
However, most professional gardeners would agree that between 8 AM and 10 AM is the best time of day to cut your grass. The reason for that is that lawns need time to heal before evening. Grass needs the benefit of the day to dry and heal before dusk settles.
Mowing the grass so early in the season, especially at a low mower setting is going to put that grass into survival stress. In March, unless it is incredibly warm in late February and into early March, the grass is still dormant or just beginning to awaken from its winter dormancy.
Cool-season grasses should typically be cut to about 3 to 4 inches high. Warm-season grasses should typically be cut to about 2 to 2 ½ inches high. The common cool-season grasses include fine and tall fescue grass, Kentucky bluegrass, and perennial ryegrass.
What Length Should Grass Be Cut for Optimal Results? Ideally, during warm weather, grass should be kept as high as possible. For most circumstances, the blades should be kept somewhere around 2 to 2.5 inches in length.
Proper Mowing
Mow the lawn as high as possible—as high as you can comfortably tolerate. A longer lawn means more leaf blade, and this provides several benefits. More leaf blade means more photosynthesis, which results in stronger, more prolific root and shoots growth.
Shorten your cool season grass to about 2.5 inches before the first frost in winter. Mow warm-season grasses to 1.5 or 2 inches in fall.
You'll know you're cutting too short if brown and tan patches begin to appear on grass blades. What Height Should Be My Goal? Once the weather warms up, most types of grass should be kept between two and two and a half inches.
If the grass is too wet, you shouldn't mow and if it's too dry you shouldn't either. Remember, mowing is a stressful event for your lawn. If you mow when it's already under stress, such as during dry spell or drought, then it will become even more stressed. You don't like to be stressed and neither does your poor lawn.
Mid-morning (between 8 and 10 a.m.) tends to be the best time of day for mowing your lawn. It allows enough time for dew to dry, resulting in strong, perky blades of grades, while avoiding the hottest periods of the day.
If you let the grass grow taller, there is no need for the grass to tiller and your lawn thins out. Fungal diseases. In our wet climate, we get a lot of fungal diseases in late fall through spring. Tall grass makes matters much worse because there is no airflow, creating a perfect microclimate for fungal diseases.
If you know a heavy rain is coming, then try to mow your lawn before the storm hits. Planning this way will save you the trouble of waiting a day or so for the grass to dry for your next mowing. For most other days, try to pick either the mid-morning or late afternoon to mow.
No Mow May was first popularized by Plantlife, an organization based in the United Kingdom, but is now gaining traction across North America. The goal of No Mow May is to pause mowing during the month of May, allowing flowers to bloom in your lawn to help early season pollinators.
Short Answer: No Mow May meant to help pollinators
Like it sounds, No Mow May means taking a break from mowing your lawn for the month of May. Coupled with that also is the idea of not using fertilizers, herbicides or pesticides throughout the month. The motivation behind the campaign is to help pollinators.
While it might be tempting to mow your lawn as soon as the rain clears, you're better off waiting until the grass is dry. Cutting wet grass can lead to plant fungal diseases, soil damage, and even mower operator injury—all of which are preventable with a little patience.
The short answer is yes, according to lawn care experts. Leaving grass clippings on the lawn can actually be healthy for the grass, as it helps build a strong and nutrient-rich soil. This practice is known as “grasscycling,” and it has become increasingly popular in recent years.
Up to 25 percent of your lawn's total fertilizer needs are supplied by clippings left on the lawn. Clippings contain 80 to 85 percent water and decompose quickly. MU research shows clippings do not contribute to thatch problems. Average mowing time can be reduced by 30 percent when grass clippings are not bagged.
Many experts say grass mulching is the best method. Leaving the clippings will save you time and energy, and it will return valuable nutrients to the lawn. Lawns love to be fed, and grass clippings contain the same beneficial nitrogen, phosphorus, and potassium nutrients as fertilizer.
