At Crann Grá, we avoid chemical pesticides. Instead, we use companion planting—grouping plants together for mutual benefit. Aromatic herbs are excellent companions, using their strong essential oils to confuse and repel pests.
For example, planting chives near roses helps prevent blackspot and repels aphids. Planting sage or thyme next to brassicas deters the cabbage white butterfly, as the strong scent masks the host plant. Planting mint near tomatoes helps keep aphids away. By incorporating these herbs into your garden layout, you create a natural shield that supports a healthy ecosystem.
