Spray Some Cinnamon On Your Lawn, & Your Grass Will Thank You. Here's Why.
If you're already feeding, mowing, and watering your lawn, there's one more natural trick that could take it to the next level — a simple cinnamon spray. The pantry staple cinnamon has natural antimicrobial and antifungal properties that can help support your lawn's health, especially when the soil is under stress.
According to a study published in Molecules, cinnamon extract helped control common soil imbalances and reduce fungal overgrowth, making it a perfect natural alternative to chemical fungicides. It works best when sprinkled lightly after events that disrupt the soil, like a heavy rain, mowing, or high foot traffic. It is because those events disturb the soil and can create damp conditions, which fungus loves. Using cinnamon helps dry out the surface and makes it harder for fungus to thrive. It's especially important if you're trying to maintain a lush, fancy type of grass that's more sensitive to stress.
Another study found that cinnamon didn't just stop harmful pathogens. It actually supported the good microbes in the soil, too. A report in the European Journal of Plant Pathology noted that cinnamon powder helped create a healthier microbial balance in the soil, which can lead to stronger, more resilient grass over time. In other words, it's not just a quick fix. With regular use, cinnamon could be one of the easiest ways to support your lawn season after season, and you can even grow your own cinnamon so you never run out.
The right way to use cinnamon for grass health
Sprinkling cinnamon powder directly onto your lawn can help in a pinch, but turning it into a spray gives you better coverage and long-lasting impact. To make a simple cinnamon spray solution, start by mixing 2 to 3 tablespoons of ground cinnamon into about a quart of warm water. Stir the mixture well, then let it sit overnight so the water can fully absorb the cinnamon's beneficial compounds. In the morning, strain the mixture through a fine mesh sieve or coffee filter to remove any remaining grit.
This step helps keep your spray nozzle from clogging. Then pour the liquid into a clean spray bottle. You'll want to focus your spray on the soil around affected areas or wherever your grass seems stressed, such as spots that stay soggy, receive too much shade, or see heavy foot traffic. Lightly spritz the soil surface, not the grass blades, and repeat the process two times a week or after rain to keep fungal growth in check. This antifungal spray for plants is gentle, natural, and works best when used consistently.
You can also use cinnamon spray as a possible insect deterrent. While it won't chase off every insect, many common lawn pests, like ants and spider mites, are sensitive to its strong scent and tend to stay away. Just keep in mind, a little goes a long way. Too much cinnamon can overwhelm beneficial microbes that actually help your grass grow.
