Companion planting is all about creating areas of plants that provide benefits to each other. In practice, this means that plants that complement each other are placed together, and those that don’t, are kept apart. By planting 'companion' plants among other plants it can help them to grow by either attracting beneficial insects, repelling pests, or by acting as a sacrificial plant to lure pests away.

Plants complement each other by:

• Reduced competition – put shallow roots beside a plant with deep roots and they will seek nutrients in different levels of the soil, allowing it to support more variety.
• Improving soil – Some plants can improve the soil for others by enriching the nitrogen content.
• Pest repellent – certain plants repel certain types of pests.

Top tips for companion planting:

• Avoid planting all of the same plants together or in rows; pests find their favourite plant and spread quickly.
• Try 'intercropping': plant fast growing edible plants between slow growing ones
• Plant herbs to repel insects
• Use tall plants to create shade for others
• Plant lots of insect and bird friendly plants throughout your garden
