Planting season is
just around the corner and if you’re anything like me, you are thinking about growing your own garden and
starting the research so that you can do it as green as possible.
Think of a garden centred around the plump tomatoes and fresh basil to be used in a delicious bruschetta, or
the carrots and beets that will make up your daily dose of harvested juice. Whatever your crops of choice,
companion planting is the concept to consider.
Companion planting is an organic method based on the idea that nature knows best how to protect itself. We
are all aware of the many micro-environments that are thriving in our backyards. These micro-environments
consist of nature’s elements working together to nurture and protect; insects, birds, sun and shade all play
their unique roles in creating healthy ecosystems. Companion planting teaches us how best to benefit from
this natural cycle by intentionally pairing plants to attract the aspects in nature that will enrich our
garden and ward off those elements that tend to be destructive.
The key concept of companion planting is diversity. Natural ecosystems thrive on diversity and work best when
they can rely on the contribution of different players. Creating diversity in your garden will not only help
you avoid potential pest problems, but it will make the best use of the space you have to work with and
guarantee an enriched soil where your plants will thrive.
By following a few simple guidelines as to which plants make the best companions you will align yourself with
nature and act as conductor. By orchestrating a harmonious grouping of vegetables, herbs and flowers that
serve and protect one another, you eliminate the need for fertilizers and pesticides.
There are an infinite number of companion neighbourhood options so it is best to start with your favourite
crops in mind and build around them. The tried and true points to keep in mind are the following:
|
• |
Achieve natural pest control by
pairing plants that attract beneficial insects with a companion that is vulnerable to harmful pests. Basil,
cilantro, chives and sage protect against pests such as aphids and hornworms. As a result they serve as great
companions to lettuce, tomatoes, beets, zucchini and carrots. |
|
• |
Neighbour plants such as green
beans, peas or beets, which enrich the soil with fixed nitrogen and minerals, with carrots, eggplant and
cucumbers — all of which require a larger intake of nutrients for healthy growth. |
|
• |
Neighbour shallow rooted plants with
deeper root companions to give ample rooting space and enable nutrients and water to be shared most
efficiently. The deeper roots are able to reach down and feed from the subsoil, leaving the surface soil
layers for the shallow roots. |
|
• |
Neighbour plants that don’t compete
for light by pairing shade-loving shorter plants with sun-loving taller companions. Low-lying lettuce is a
good companion for taller tomato and pepper plants. |
|
• |
Generously place ally plants around the garden to keep your key plants pest-free. This is one of the most beneficial elements of companion planting. A few of the tried and true garden ally heavyweights are marigolds, basil, mint and nasturtiums. |
Companion planting is a simple, natural approach that allows us the ability to grow a vibrant garden without
having to rely on chemicals to do the work that nature itself can achieve. By considering which plants you
pair up and building neighbourhoods that benefit from one another, you will get the most out of your
companion-planted garden. Whatever approach you take, get your feet into the soil this season and be
creative. With numerous sources online you are sure to have all the information at your fingertips to create
a green garden of companions!
