For many gardeners, the summer just isn’t complete without a delicious crop of tender Runner Beans. They are such a productive crop and really easy to grow. Don’t be put off if your plot is tiny - Runner Beans are the perfect space saving crop and grow equally well in large patio pots. In fact, with their ornamental, heart shaped leaves and pretty, nectar rich blooms, they look perfectly at home in the flower border!

Grow Runner Beans in a sunny or semi shaded spot with shelter from strong winds. Runner Beans are happy in any fertile, well drained soil. It’s a good idea to prepare the site in spring by digging it over and adding some well rotted organic matter, although it’s best to avoid adding manure immediately before planting as this will promote lots of foliage rather than beans.
From April, you can start Runner Bean seed off in small pots and transplant them later on. Simply fill a pot with seed compost and make a hole of about 5cm (2") deep. Drop in a Runner Bean seed before backfilling the hole with compost and watering the seed in.
Runner Beans will germinate in about a week and grow surprisingly quickly. You will need to harden Runner Bean plants off for 7 to 10 days before transplanting them outdoors. You can tell when to plant Runner Beans outdoors by checking that they are fully rooted in to their pots, and keeping a close eye on the weather to ensure that all risk of frost has passed. In most parts of the UK, this will be from around the end of May.
Alternatively you can sow Runner Bean seed directly in the ground outdoors from May to July. Sow them at a depth of 5cm (2") and a distance of 30cm (12") apart in adjacent rows that are set about 45cm (18") apart.
Where space is limited, you can try planting Runner Beans against a wigwam structure - they make an eye-catching feature in your flower borders. They are perfectly happy growing in containers too, so you can even harvest a tasty crop from your patio.
It’s a good idea to sow a few extra seeds at the end of each row, as spare plants for filling gaps in the row where seeds have failed to germinate. If these plants aren’t needed then you can give them to your friends!
Runner Beans require support from garden canes, strings or netting. Ideally these should be put in place at the time of planting, but they can be added after germination if necessary.
The most commonly used runner bean support is an A-frame of garden canes which spans two adjacent rows of Runner Beans. Insert a tall garden cane next to each seedling and then tie each cane to the one opposite with garden twine to create a tunnel. A supporting cane run along the top of the framework will help to hold the structure rigid. The beans will naturally twine their stems around the canes as they grow.
When growing Runner Beans in containers, a wigwam framework is preferable. This can be created from a circle of garden canes, tied together at the top.
If you are growing Runner Beans against walls and fences it is easiest to attach a piece of plastic horticultural mesh which will create a perfectly adequate support.
Throughout the growing season you will need to water your beans regularly, particularly as they start to develop flowers. A lack of moisture is one of the main reasons why Runner Bean flowers can fail to set pods. A liquid feed applied every 14 days will also help to maximise your crop.
Pinch out the growing tips of the plants once the stems reach the tops of their canes to divert their energy onto producing beans rather than growing tall.
Runner Beans can be harvested from July when the pods reach 20cm (8") long. Pick beans every 2 or 3 days to ensure that they are tender and prevent them becoming stringy. The more you pick, the more pods will be produced! Don’t worry if you end up with a glut of Runner Beans - they can easily be frozen and enjoyed later in the year.
Runner beans are a cool-season crop so they grow particularly well in the UK. Most people will not experience many serious problems with their Runner Beans at all. Nonetheless, gardeners do sometimes find that their crop may fail to set pods, particularly early on in the season.
Plants and gardens have always been a big part of my life. I can remember helping my Dad to prick out seedlings, even before I could see over the top of the potting bench. As an adult, I trained at Writtle College where I received my degree, BSc. (Hons) Horticulture. After working in a specialist plantsman's nursery, and later, as a consulting arboriculturalist, I joined Thompson & Morgan in 2008. Initially looking after the grounds and coordinating the plant trials, I now support the web team offering horticultural advice online.
