Lawn diseases are no joke, and when your grass is struggling with brown patch, dollar spot, fairy ring, or other diseases, you need to take a break from mowing.
Mowing brown grass can be beneficial, even if it appears to be dormant or dead. Here are some considerations: Promoting Recovery: If the grass is still growing, mowing can help remove dead grass blades and allow sunlight to reach the healthier parts of the plant, promoting recovery.
If the weather has been super dry and cooler than 50 degrees Fahrenheit, it is okay to stop mowing. Without the proper moisture and cool temperatures, the grass will not grow and therefore, will not need mowing. Once again, depending on the climate, this window is normally around late October through early December.
If your grass is actually dead, there's nothing you can do to bring it back other than plant new grass. Brown grass, however, can green up following proper care. Oftentimes, that just means water, nutrients, and cooler temperatures for northern lawns and warmer temperatures for southern lawns.
Both the University of Rhode Island Landscape Horticulture Program and Ohio State Extension Master Gardener agree that it is better to mow grass when it is dry, but the only reason seems to be that the cut grass blades tend to stick together when they are wet and leave clumps of unsightly grass piles on your lawn.
The warm, dry California air and plenty of sunlight mean lawns usually take only about a day (or sometimes several hours) to be mower-ready.
No Mow lawns may require occasional mowing during the first two years of establishment to control weeds, especially with lawns that are seeded in spring. Most annual weeds can be controlled by mowing at a height of four inches in the first growing season.
Consistent watering is crucial in turning your brown, lifeless lawn into a vibrant carpet of rich green. Grass seed must have consistent moisture to germinate and establish healthy roots, so respect this critical step. Water your lawn daily so the soil stays consistently moist. If needed, water twice a day.
When your whole lawn is the same brown color, the grass may be dormant. However, if there are areas or circles of brown grass, that can point to these spots being dead. Before you count this grass out, you'll need to rule out possible pests and disease that can cause similar symptoms.
Off-color or Discolored Grass
Your lawn should be a deep green color. But if it looks yellow, brown, or even pale in nature, it could be getting too much water.
Have you heard about “No Mow May?” Many people have committed to not mowing their yards in May, allowing flowering plants to grow to help provide food for pollinators. Before you stow away your mower for May, let's look at what options you can take to help pollinators this Spring.
Yes, it is illegal not to mow your lawn if the height of your grass and weeds exceeds the maximum local laws require. Many cities and counties nationwide have nuisance ordinances that set maintenance requirements for residential properties, which often refer to: The maximum grass height.
Mowing your lawn too short, also referred to as “scalping,” can cause visible stress to your lawn. Scalping stresses the grass blades by reducing the leaf surface it needs for photosynthesis. It also exposes the soil to sunlight, promotes weed growth, heat stress, and leads to weak root systems.
Dormant grass can start to green up within 7–10 days with proper watering and care. If the grass is dead, it requires reseeding, fertilization, and consistent maintenance, which could take weeks or even months.
Brown spots that appear after mowing are often caused by a dull mower blade. Dull blades will shred the grass instead of cutting it cleanly and will damage the ends. This causes the tips of the grass to die and turn brown. You can easily fix this by sharpening or replacing the blades on your mower.
The grass will break dormancy and begin growing again when the temperatures and/or rainfall levels become more ideal for it. Note that when dormancy ends, grass leaves that have turned brown won't revive, but new leaves will appear.
By doing an early spring mowing and removing the brown tips off of your grass, this naturally brings out the greener grass blades, and it may even help to stimulate growth. While you'll still need to plan on simply giving the grass more (WARMER) TIME to green up, a good mowing certainly won't hurt, at any rate.
Try the Tug Test
One of the first things that you can use to figure out if grass is alive is the “tug test.” Find a section of brown grass and tug. If it comes out easily and there is no sense of resistance, it's probably dead in that area.
While truly dead grass cannot be revived, brown, patchy, or dormant grass can often be rejuvenated with the right care and attention. Identifying the root causes of grass issues, such as drought stress, weed competition, pests, diseases, or poor soil quality, is crucial before implementing revival strategies.
The timeline largely depends on the burn's cause. Moderately-burnt grass needs about one week to grow back, while heavily-burnt grass takes about one month to reestablish. The recovery time for burnt grass depends on the type of grass on your lawn and the leading cause of the burn.
Water Wisely
Many of us water too often and too long. Most lawns need to be watered no more than three days a week in the spring as well as in the summer and two days a week in the fall. This watering schedule is recommended under normal water supply conditions.
The history. 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.
However, avoid mowing dormant grass. The blades are not growing, and mowing can cause stress that isn't good for dormant grass.
It's a catchy name for a movement that aims far beyond not mowing yards for a few weeks. It's a chance for gardeners to consider how they can better support pollinators — from mowing less to creating meadows.
