Companion planting is an organic method of maintaining a natural balance in your garden, aiding pollination and keeping pest numbers down.
Common plant combinations include growing nasturtiums to deter aphids from attacking your beans, and planting alliums around carrots to ward off carrot root fly.
Most companion plants are strongly scented and confuse pests looking for their host plant. Others attract beneficial insects, such as ladybirds and lacewings, which prey on aphids.

Borage, Borago officinalis is an attractive plant with hairy leaves that have a slight cucumber flavour. Its delicate blue flowers are a magnet for pollinators, such as bees, butterflies and hoverflies, which pollinate crops. If planted nearby, borage can prevent attack from tomato hornworm and is said to improve the flavour of strawberries.
