A few choices that fall in the repelling category include rosemary and thyme (repels cabbage moth), sage (repels carrot rust fly), asparagus (repels harmful nematodes), yarrow and chives (repels aphids) and cilantro (repels potato beetle) – keeping in mind that the repellent quality is not an impervious barrier.Īs far as fixing nitrogen is concerned, all beans (broad, soya, scarlet runner, bush and pole) and peas (green, snap, snow) will do the trick, although that does not always make them the best companion for every vegetable, so do a little research before designing your planting scheme. So your best bet with this class of plants is to give them their own growing space away from the vegetable garden. In the realm of edibles, a few common examples of these would include black walnut (toxic to tomatoes, peppers, potatoes and other members of the nightshade family), black elderberry ( Sambucus nigra) and fennel, although the latter will attract beneficial insects and pollinators. There is one more category that includes allelopathic plants, or those that have developed and release natural toxins to inhibit the growth of adjacent species.

In the simplest of terms, it works by one of several means: providing additional pollen or nectar to attract pollinators and increase yields drawing pests away from the desired vegetable through trap cropping physically shielding crops from wind or excessive sun (not every plant likes full sun) providing nutrients by means of nitrogen fixing or even by simply repelling unwanted pests or animals. I know that some gardeners believe it to be nothing more than a gimmick to sell books such as Carrots Love Tomatoes or Roses Love Garlic (both written by Louise Riotte), but we now have a lot of scientific proof verifying the benefits of pairing plants. I thought I would start the new year by encouraging all of us to work with nature in 2018 – and there is no better way than with companion planting. Maple Ridge and Pitt Meadows Tourism Guide.
