Ditch Your Lawn for a Wildlife Garden
Here in Cumberland County, we love our outdoor spaces. But did you know that the traditional, manicured green lawn takes a significant toll on our local environment? Nationwide, turfgrass covers roughly 40 million acres, requiring gas-powered equipment that emits millions of tons of air pollutants annually.
Even closer to home, the weedkillers and fertilizers used to keep lawns pristine easily wash into our storm drains, eventually making their way into Casco Bay, local lakes, and rivers.
The good news? You can make a massive difference right in your own backyard. By converting even a portion of your lawn into a wildlife-friendly native garden, you can help combat the steep decline of regional birds and pollinators.
Here is a simple, step-by-step guide to transforming your yard into a conservation haven:
1. Start Small
Don’t worry about digging up your entire yard overnight! Avoid potential weed and erosion issues by picking a manageable pilot spot—like a strip along a fence, a section by your sidewalk, or a "soft landing" garden bed around the base of a mature tree.
2. Plan with Maine Natives in Mind
Native plants have spent millennia adapting to our local climate and soil conditions, making them absolute magnets for local wildlife. For instance, monarch caterpillars depend entirely on native milkweeds to survive. Before buying, assess your chosen spot: Is it sunny or shady? Is the soil sandy, loamy, or frequently wet?
3. Clear the Grass Safely
There are plenty of low-impact ways to say goodbye to your turfgrass without relying on harsh chemicals:
Sheet Mulching: Cover the grass with cardboard to block out the sunlight.
Solarization: Lay clear plastic over the area during the peak of summer to bake the turf underneath.
Manual Removal: Use a shovel or rent a sod cutter for immediate results. If you choose cardboard or plastic, you can leave the dead grass underneath to decompose naturally, adding rich organic matter back into your soil.
4. Source Your Plants Smartly
You might not always find a robust selection of native plants at standard big-box garden centers. Keep an eye out for local plant swaps, regional native plant nurseries, or community plant sales. To save on costs, look for plugs—small, young plants that grow rapidly once they hit the ground.
5. Let Them Touch
When you plant, skip the extra commercial garden soil if your choices already match your yard's natural conditions. Space them so that as they mature, they grow into one another. As our master gardeners like to say, "Plants want to touch each other, not look at acres of mulch." A dense native bed means fewer weeds for you to pull in the long run! Remember the classic perennial rule: the first year they sleep, the second year they creep, and the third year they leap.
6. Practice "Lazy" Fall and Winter Cleanup
Once your garden is established, it will require very little watering outside of severe droughts. When autumn arrives, resist the urge to cut everything down to the ground. Leave the plant stems and fallen leaves intact through the winter; our native bees, butterflies, and fireflies rely on that leaf litter and hollow stems to safely overwinter.
Ready to get your hands dirty? Shrinking your lawn is a powerful way to protect Maine’s water quality and bring the joyful sounds of birds, frogs, and pollinators right to your doorstep.
