Companion Planting - Best plants to grow together in containers

Certain plants can be grown together so that they benefit each other in some way. Such companion plants are believed to encourage beneficial insects and help repel or deter pests by masking the smell of a host plant, or even sacrifice themselves by attracting pests away from a neighbouring crop.

In this article, we will talk about the best plants to grow together in containers.

What is companion planting?

Companion planting means placing plants together which are beneficial to each other in some way, this could be by deterring pests (aphids, whitefly, blackfly, hornworms), improving soil nutrients, attracting beneficial insects (ladybirds, hoverflies, lacewings) that will help with pollination, or by providing a support structure in which to climb on.

An easy way to do this is to mix things up by placing pots of different crops next to each other and planting combinations of crops in larger pots.

Companion planting helps to maximise your space by mixing vertical and bush plants together in one container.

Beans and Sunflowers

Runner beans and Sunflowers are some of the most rewarding crops to grow together demanding only a regular supply of water in exchange for beautiful flowers and generous supplies of beans.

Beans and Sweet corn

Beans can climb up the sweet corn, but also the bushy habit of the beans provides a living mulch around the base of the sweet corn, keeping the roots cool, the canes stable, and the compost moist. Water and feed these plants regularly. Both corn and beans are thirsty plants and may need watering twice a day in hot weather.

Companion planting is very important for any garden. By growing a diverse range of plants you are encouraging beneficial insects and natural predators into your garden.
