Gardening is one of life’s simple joys, but anyone who spends time outdoors knows that ants can quickly become unwanted visitors.

They disturb soil, cluster near roots, and sometimes protect aphids that damage plants. Many people turn to strong sprays to get rid of them, but my nana always believed in gentle, natural methods.

Her favorite? Cinnamon — a household spice that quietly keeps ants away without harming the garden.

Her method was simple: sprinkle a thin line of ground cinnamon around garden beds, flower pots, or entry points where ants tend to gather. The strong scent naturally disrupts their pheromone trails, making it difficult for them to navigate. Over time, the ants move elsewhere, leaving the plants undisturbed. Use about a teaspoon per foot of soil, and reapply after heavy rain to keep the barrier effective.

Ants often appear where there’s moisture or easy access to food, but cinnamon helps interrupt their activity safely. It’s biodegradable, pet-friendly, and perfectly safe near vegetables — just avoid sprinkling it directly on leaves. Gardeners who’ve tried this method often notice fewer ants and healthier plants over time, all without reaching for chemicals or expensive treatments.

Cinnamon is part of a growing list of simple, eco-friendly garden tricks — like coffee grounds to deter slugs or crushed eggshells to discourage snails. My nana’s timeless approach reminds us that sometimes the most effective solutions aren’t found on a store shelf, but right in the kitchen. A little patience, a little cinnamon, and a touch of old-fashioned wisdom can go a long way in keeping any garden peaceful and thriving.
