Vegetable Companion Plants

Vegetables are one of our primary sources of food and therefore I usually arrange my companion plants around my vegetables which are planted in groups for easy annual rotation.  Every vegetable bed should have some herbs, nitrogen or nutrient accumulating plants, pollinator plants like flowers and insectary plants.

Companion Planting is an integral part of permaculture and a holistic approach to gardening where you plant different crops in proximity for maximising the use of space, providing nutrients, shade or support, increasing crop productivity, attracting beneficial insects, pest control / repelling pests, pollination or providing a space for beneficial creatures. The concept is an ongoing process of living and learning with nature and increasing biodiversity to support a sustainable Eco system.  Below is a quick reference guide for companion planting with vegetables:
