Tree Companion Plants

Trees are often features in gardens and therefore companion planting guilds are usually arranged around your trees.  Every thriving plant guild should include pollinator plants (like herbs and flowers), insectary plants (like yarrow and artichoke), nitrogen or nutrient accumulating plants (like comfrey), ground covers (like nasturtiums or sweet potatoe) and green manure plants (like legumes).

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 tree companion planting:
