Key Takeaways:
- An eco lawn is a sustainably maintained lawn that minimizes chemical inputs, conserves water, supports biodiversity, and reduces carbon emissions.
- Lawns provide measurable environmental benefits including cooling, water filtration, erosion control, and carbon sequestration.
- Simple practices like mowing less often, grasscycling, and planting native species can significantly reduce your lawn's environmental impact.
Lawns aren't just ornamental: exploring the environmental benefits
Many people take pride in having the most visually appealing lawn on the block, and while aesthetics are important, the environmental benefits of lawns go beyond just looks. An eco lawn—a sustainably maintained lawn that minimizes chemical inputs, conserves water, supports biodiversity, and reduces carbon emissions—can have a significant positive impact on the environment.
Key Environmental Benefits of Lawns
Here's how an environmentally friendly lawn contributes to a healthier planet:
- Cooling Effect: Lawns provide a cool, safe surface for recreational activities, reducing the need for artificial and less eco-friendly yard enhancements. According to the University of Minnesota, lawns can moderate air temperature significantly compared to paved surfaces.
- Water Filtration: Grass decreases water runoff and filters water before it enters the drainage system. Grass plays a crucial role in taking up nutrients, filtering sediment, and slowing down water movement, which helps more water enter the soil rather than running off.
- Erosion Control: Lawns reduce soil erosion effectively by creating a deep-rooted perennial ground cover.
- Biodiversity Support: Compared to paved spaces, lawns are teeming with life, from insects, earthworms, and pollinators to bacteria, fungi, and soil-thriving critters.
- Carbon Sequestration: Through photosynthesis, grass removes carbon dioxide from the air, repurposing it to grow new leaves and roots, which helps in mitigating climate change. Research from the University of Minnesota Turfgrass Science program confirms the potential of turfgrass to sequester carbon and offset greenhouse gas emissions.
Sunday Tip:
Carbon sequestration is moot if you don't take steps to minimize emissions involved in lawn maintenance. Do your part by mowing less often, keeping your irrigation systems in good shape, applying fertilizers responsibly, and avoiding pesticide use when possible.
How to Grow a Sustainable Lawn
At Sunday, growing dense, healthy turf is fundamental—not just for its beauty but for its environmental benefits. We advocate for deep but infrequent watering, which encourages deeper roots that are more resourceful and less reliant on human inputs. The result? More carbon sequestration, less water use, and less fuel consumption. Win, win, win!
Here are sustainable lawn practices we use to reduce the net carbon impact of our lawns:
Mow Higher and Less Often.
To temper fuel consumption, you can simply mow less often. The longer you let your grass grow, the longer your roots will grow, which increases the rate of carbon sequestration!
Leave Grass Clippings on the Lawn.
Grasscycling—leaving grass clippings on your lawn to decompose and return nutrients to the soil—reduces the need for fertilizers and cuts back on landfill waste. Studies suggest grasscycling can reduce fertilizer needs by up to 25%.
Sunday Tip:
Did you know? Lawn clippings comprise the largest single waste product in many city landfills!
Feed Your Lawn Only What It Needs
Less is more! We follow MLSN (Minimum Level of Sustainable Nutrition) guidelines, which means applying targeted nutrient doses to your soil based on soil testing. This reduces fertilizer waste, fertilizer leaching, and the fuel consumption associated with fertilizer production.
Plant Native Gardens
Sunday is more than just a lawn company! We're big fans of planting pollinator gardens.
Grow Clover
In addition to being friendly to pollinators, clover has a built-in mechanism for converting atmospheric nitrogen into nutrients that it—and the surrounding grass—can use. We add a premium microclover to our Lucky Lawn grass seed to make it easy for you to grow it.
Rethink Your Relationship with Pests
Integrated Pest Management (IPM) calls for using pesticides only as a last resort, which is better for pollinators and reduces fuel consumption associated with pesticide production.
Sunday Tip:
You can support pollinators in your lawn! Leave flowering plants for pollinator forage. Plant clover and raise the mowing height to provide season-long blooms. If you do need to spray pesticides, make sure to remove flowers (by hand or by mowing) prior to spraying so you don't harm critical pollinators like birds, bees, and butterflies!
Frequently Asked Questions
How does grass help the environment? Grass helps the environment by cooling the air, filtering water runoff, preventing soil erosion, supporting biodiversity, and sequestering carbon dioxide from the atmosphere.
What is grasscycling? Grasscycling is the practice of leaving grass clippings on your lawn after mowing to decompose and return nutrients to the soil, reducing the need for fertilizers.
Does mowing less help the environment? Yes, mowing less often reduces fuel consumption and allows grass to grow taller, which promotes deeper root growth and increases carbon sequestration.
What is an eco lawn? An eco lawn is a sustainably maintained lawn that minimizes chemical inputs, conserves water, supports biodiversity, and reduces carbon emissions through responsible lawn care practices.
