Keeping your garden tidy at this time of year can seem like a tedious task, especially with the high winds and torrential rain. One area that is particularly challenging to maintain is your lawn. Keeping your grass looking its best isn’t a simple chore. It’s one that requires commitment, and at times, you will feel like you’re fighting a never-ending battle.

Moss, fungus, and all manner of insects and animals try to damage your lawn. They are responsible for ruining your picture-perfect grass, as the pests can make it look patchy and uneven.

That’s why gardeners are now being urged to sprinkle cinnamon powder on their lawns. It’s cheap and has been branded as an ‘easy way to instantly boost the look of your lawn’ According to experts, the cooking product repels pests, stops fungus and mildew and boosts grass growth, all at once.

The Express reports that the sweet spice contains some very useful properties, making it a perfect lawn-fixing feed ingredient without the need for chemicals.

According to OutdoorGuide.com, cinnamon is a good eco-friendly alternative to spraying chemicals on a lawn, as it repels insects and pests, including ants, aphids, and mosquitoes. However, it will also deter squirrels from digging in your lawn to bury food.

It says: “Sprinkling cinnamon on your grass isn’t just a quirky garden trick; it’s a natural defence against a host of unwanted critters, from industrious ants to delicate aphids to buzzing mosquitoes.

“Research, like a study featured in Molecules, suggests that cinnamon possesses remarkable properties that not only repel pests but can even deter insects from laying their eggs when applied in larger quantities. This repellent effect can be attributed to the presence of potent compounds, such as cinnamaldehyde and terpenoids, which are known for their insecticidal properties.

“Cinnamon isn’t just a one-trick pony when it comes to pest control. It boasts a versatile repertoire, capable of warding off and even deterring larger nuisances like squirrels and raccoons, making it a comprehensive solution for safeguarding the grass in your garden.”

It doesn’t stop there, because cinnamon’s anti-fungal properties also block the growth of moss, fungus and other harmful bacteria that would mean to do your lawn harm.

It adds: “Cinnamon doesn’t just stop at repelling pests; it’s also a powerful ally in combating harmful bacteria and fungi that threaten the health of your grass, as shown by a study in Agricultural and Food Chemistry.

“This aromatic spice harbors remarkable antimicrobial properties, primarily attributed to compounds like cinnamaldehyde. When sprinkled onto your grass, cinnamon acts as a natural barrier, inhibiting the growth of detrimental bacteria in the soil.”

Not only this, but it can stop mildew, and all the while, cinnamon can also stimulate plant growth for your grass.

Taken altogether, cinnamon is nothing short of a garden superfood, able to boost grass growth, repel pests big and small and stop fungus, moss and mildew.
