No Mow May: Pros and Cons of Letting Your Lawn Grow Wild

May 2025 Lawn Care Tips

As spring turns into summer, many homeowners start thinking about lawn care and getting back into a regular mowing routine. But what if you took a break and let your grass grow wild for a month? That's the idea behind No Mow May, an environmental initiative that encourages people to skip mowing for the entire month. Here's an honest look at the pros, cons, and some practical alternatives.

The Case for No Mow May

  1. Promotes biodiversity Letting your lawn grow creates habitat for a wider range of plants and animals, including pollinators like bees and butterflies. Even a month of growth can make a real difference for local ecosystems.
  2. Saves time and money Skipping a month of mowing means one less recurring task and, if you hire a professional service, one less bill. It's a small break that adds up.
  3. Reduces carbon emissions Gas-powered lawn mowers contribute to air pollution. Reducing how often you run one is a straightforward way to lower your carbon footprint, even if only by a little.

The Case Against No Mow May

  1. May violate local regulations Many municipalities have ordinances that require lawns to be kept below a certain height. Before you skip May, check with your local government to make sure you won't end up with a fine.
  2. Can lead to overgrowth that's hard to manage A full month of unchecked growth can make June mowing difficult, especially if you're cutting more than a third of the blade height at once. Have a plan for getting back on track gradually.
  3. May attract pests Tall grass creates habitat for ticks and mosquitoes. If you have kids or pets who use the yard regularly, this is a real consideration worth weighing carefully.

Alternatives Worth Considering

If you like the idea behind No Mow May but want to keep some control over your yard, these are practical middle-ground options.

  1. Mow less frequently You don't have to go the full month without mowing. Simply stretching your schedule from weekly to every two or three weeks still gives pollinators more time with flowering plants while keeping your lawn manageable.
  2. Plant native wildflowers Dedicating a section of your yard to native wildflowers is a longer-term way to support local pollinators without letting the whole lawn go. It also tends to look more intentional than overgrown grass.
  3. Use a manual reel mower If reducing emissions is your main goal, a push reel mower does the job without gas or electricity. They're quieter, require almost no maintenance, and work well on smaller lawns.
