Nature's Little Helpers

Everybody needs friends – including plants! And the best plant-friends are the ones that keep pesky garden pests at bay. Putting these pest-repellent plants in your garden along with your favourites is known as companion planting.

Companion plants control pests in a variety of ways. ‘Masking’ plants produce strong, volatile oils and scent that mask the plants the pests might be looking for. ‘Repellent’ plants produce a scent or taste that is so bitter that it drives unwanted garden pests away.
