Weed suppression: how your garden benefits from natural control

One of the biggest challenges for every gardener is dealing with invasive weeds, which can compete with your desired plants for nutrients, sunlight, and water. However, there is a helpful technique called seasonal rotation that can provide a satisfying gardening experience. With the sense of accomplishment that comes from seeing your plants thrive and your landscape flourish, controlling invasive weeds can be easier without compromising the beauty of your garden.

Companion planting

One effective way to naturally suppress weeds in your garden is through companion planting. This technique involves growing compatible plants next to each other to create a mutually beneficial environment. By carefully selecting and pairing plants that have symbiotic relationships, you can reduce the space available for weeds to grow.


Mulching is another excellent method for weed suppression. By applying a layer of organic material such as straw, wood chips, or leaves to the soil surface, you create a physical barrier that prevents weed seeds from germinating and penetrating the sunlight they need to grow. Additionally, mulch helps retain moisture in the soil, reducing the need for frequent watering and further inhibiting weed growth.

Using plants to suppress weeds

Instead of constantly battling with weeds, why not let plants do the job for you ? Certain plants have natural weed-suppressing properties that can be harnessed to benefit your garden. Here are some key factors to consider :

Selection of plants

When choosing plants for weed suppression, opt for species that have vigorous growth habits, dense foliage, or the ability to release chemicals that inhibit weed germination or growth. Examples of such plants include yarrow (Achillea millefolium), marigolds (Tagetes spp.), and buckwheat (Fagopyrum esculentum).

Planting techniques

To effectively utilize weed-suppressing plants, it's important to plant them in a way that maximizes their potential. Interplanting, where different species are grown together in close proximity, creates a dense canopy that shades out weeds and reduces their ability to establish. Additionally, using plants with varying heights can help create a layered effect, further preventing weed growth.


Regular maintenance is vital for successful weed suppression using plants. Ensure that you promptly remove any weeds that manage to emerge before they can spread and compete with the desired plants. Additionally, providing proper nutrients and water to your weed-suppressing plants will help them thrive and maintain their competitive edge against unwanted weeds.

Minimizing soil disturbance

Another effective strategy for weed suppression is minimizing soil disturbance. Traditional gardening practices such as tilling and excessive digging can inadvertently bring weed seeds to the surface, where they can germinate and grow. By adopting a minimalist approach to soil disturbance, such as the technique of no-dig gardening, you can maintain the soil structure, preserve beneficial microorganisms, and reduce the chances of weed seed activation.

By adopting labour-efficient gardening techniques, integrating companion planting and mulching, utilizing weed-suppressing plants, and minimizing soil disturbance, you can create a garden that is not only visually appealing but also free from the constant battle against weeds. Embrace a sustainable permaculture landscape and experience the joy of a thriving garden without the need for harsh chemicals or excessive manual labour.
