Runner beans are a delicious veg plot staple – they’re one of the easiest crops to grow and produce an abundance of long green pods over several months. Most varieties are climbers, grown up tall canes, producing large harvests in a small area. A few dwarf varieties are also available, ideal for large containers. Pick when young, for tasty stringless beans.

Sow
Runner beans are tender plants that won’t survive frost, so for an early crop sow indoors in late spring. You can also sow outdoors in early summer. Alternatively, young plants can be bought from garden centres and online suppliers in spring, ready for planting outside.
Most runner beans are climbers – they need tall, sturdy supports and do best in the ground, but can also be grown in large containers. As they grow vertically, climbers produce a large crop in a small area of ground. There are also some dwarf varieties – these are quick to grow, but produce a smaller crop. They are useful for raised beds and containers, and for gardens in exposed sites. Climbing beans take longer to reach cropping stage, but produce beans over a longer period, from mid-summer to early autumn if picked regularly.
Runner beans are attractive as well as productive, with red, white or bi-coloured flowers, depending on the variety.
You’ll find a huge range of varieties available as seed in garden centres and online. Look in particular for varieties with an RHS Award of Garden Merit (AGM), which shows they performed well in trials – see our list of AGM fruit and veg.
Sow indoors
If you have space, start runner beans off indoors – on a sunny windowsill, in a propagator or in a greenhouse – from mid-April to May. This will give you an earlier crop. Choose pots 7–8cm (2.5–3in) wide and fill with moist multi-purpose compost. Sow one bean into the centre, 5cm (2in) deep, and water well.
Keep in a warm, bright place, at over 12°C (54°F). Seedlings will grow rapidly and need watering regularly.
The young plants can be transplanted outside once all risk of frost has passed, usually in late May/early June – see Plant outside, below.
Sow outdoors – in containers
You can sow seeds outdoors into pots of multi-purpose compost in spring – either into small pots for transplanting into the ground later, or into large containers as their final growing site.
Sow one bean per small pot, 5cm (2in) deep, and place in a coldframe or sheltered position. Once the plants reach 8cm (3in) tall, in June or July, plant them into their final positions – see Plant outside, below.
Alternatively, sow into large containers, positioned in a sheltered, sunny spot, as their final growing site. For dwarf beans the container should be 30–45cm (12–18in) wide, and for climbing beans 75cm (30in) wide and 45cm (18in) deep – a large tub or half-barrel is ideal.
Simply sow the seeds direct into the container, spacing them 15cm (6in) apart. Insert a wigwam of 1.8m (6ft) canes to support climbing varieties (see Grow below), and choose a heavy container to keep it from toppling over. Dwarf beans don’t usually need support and look great cascading over the sides.
Sow outdoors – in the ground
Runner beans thrive in rich, deep, fertile soil in full sun. If possible, it’s best to improve the soil with organic matter the autumn before sowing. Alternatively, it can be done a couple of weeks beforehand, to give time for the ground to settle. A pH of 6.5 (slightly acid) is preferable – add lime if your soil is more acidic.
Seeds need warm conditions to germinate, so wait until all risk of frost has passed and your soil has reached 12°C (54°F) – usually by mid-May in the south of the UK, and two weeks later in the north. If your soil is heavy and wet, it can be pre-warmed in early spring by covering it with clear plastic or cloches for about four weeks before sowing.
It’s also best to put the supports in place first – usually tall bamboo canes in a wigwam or double row (see Grow below).
Sow the large seeds individually 5cm (2in) deep – two at the base of each cane, which should be spaced 15cm (6in) apart. Thin to one seedling per cane, and protect plants from slugs and snails.
When sowing dwarf runner beans in the ground, allow 30cm (1ft) between plants and 50cm (20in) between rows.
If you sow one batch early (indoors in April/May), you can also sow a later batch outdoors in July, to prolong your harvests, allowing you to gather beans until the first frosts.
Plant outside
Wait until after the last frost before planting indoor-raised or bought young plants outside. Then harden them off to acclimatise them to outdoor conditions for a couple of weeks, either by putting them in a coldframe or placing them in a warm, sheltered spot, covered with fleece.
If planting in the ground, enrich the soil with well-rotted manure or garden compost – ideally at least two weeks before planting, to give the ground time to settle. Even better, do it the autumn before planting. When growing in rows, the traditional method for preparing the soil is to dig a bean trench:
-
Mark out a line, then dig a trench 90cm (3ft) wide and 60cm (2ft) deep. Loosen the soil in the base by forking it over
-
Scatter well-rotted manure or home-made garden compost in the base of the trench and mix with the soil from the trench. Return the improved soil to the trench
-
Add pelleted poultry manure at the manufacturer’s recommended rate
With climbing beans, it’s also best to put the supports in place before planting – see Grow, below.
Once your bean plants are hardened off, plant them into their final growing position, in the ground or in a large container, in a sunny, sheltered spot. Water the plants well, both before and after planting.
Plant one climbing bean plant at the base of each cane, and loosely tie their stems to the canes to get them started. When planting dwarf beans, space them 30cm (1ft) apart.
If planting in a container, choose multi-purpose or loam-based compost. Containers should be at least 30–45cm (12–18in) wide for dwarf beans, and 75cm (30in) wide and 45cm (18in) deep for climbing beans.
Grow
Supporting runner beans
Runner beans need tall, sturdy supports to climb up. The traditional method is to grow them up a double row of bamboo canes (1.8m/6ft tall), with 45–60cm (18in–2ft) between the two rows. Space the canes 15cm (6in) apart within each row and slope them inwards, then tie near the top to a horizontal cane, to form a sturdy A-frame. If growing more than one double row, allow 1.5m (5ft) between them.
Alternatively, create an X-frame by sloping the canes at a sharper angle so they cross in the middle. Tie them at the centre, and add a horizontal cane to link them all together and increase stability. An X-frame takes up more space, but picking is easier and cropping is usually better.
If you don’t have room for a double row of canes, you can make wigwams. Again, use 1.8m (6ft) canes, four or five per wigwam, spacing them 15cm (6in) apart at the base. Tie the tops of the canes together – or use cane support rings or ceramic finials to hold the canes together. Wigwams make an attractive feature in a border or veg plot and also work well when growing in containers.
Loosely tie young plants to the canes to get them started – after that they will climb naturally. Remove the growing point once the plants reach the top of their support. This encourages side-shoots and prevents plants becoming top-heavy.
Another support option is to use 10cm (4in) polyethylene pea/bean netting, secured to tall posts or placed over a frame.
Dwarf beans don’t usually need support, although you can insert short twiggy sticks between them to keep them upright and lift the beans off the ground.
Watering and mulching
Runner beans are thirsty plants and crop best when watered regularly, especially once they start to flower and form pods. You will typically need to apply 5–9 litres (1–2 gallons) of water per square metre/yard every three to four days. Regular and generous watering is particularly important for plants growing in containers, which dry out more quickly.
Spread a thick mulch of well-rotted manure or mushroom compost over the soil in July to help hold in moisture.
Encouraging pods to form
Runner bean flowers sometimes fail to ‘set’ (produce pods) – there are several possible causes and solutions:
-
Ensure the soil is constantly moist and doesn’t dry out. Add mulch after planting and water regularly and generously, ideally in the evenings.
-
Flower set is better in alkaline, chalky soil. If your soil is neutral or acidic, try applying lime.
-
If this is a recurring problem and you live in a mild area, try growing varieties with some French bean parentage, which set pods more easily in warmer summers. Examples include ‘Firestorm’ and ‘Moonlight’.

Harvesting
Cropping starts around mid-summer, depending on the variety and when the seeds were sown, and continues for eight weeks or more if harvested regularly.Pick pods when young and tender, about 15–20cm (6–8in) long. The pods should snap easily and the beans inside should still be small and pale in colour.
Regular harvesting – ideally every two to three days – is essential to prevent any pods reaching maturity. Once this happens, plants will stop flowering and no more pods will form.
Recommended Varieties
Common problems
Runner beans are one of the easiest vegetables to grow. However, a few pests and diseases can be problematic, one of the most common being black bean aphids. Young plants also need protection from slugs and snails.
Occasionally, fungal or bacterial diseases such as rust or halo blight can develop, while in warm, dry conditions red spider mites may get established.
The southern green shield bug is a relatively new pest found on runner beans and – although only in certain locations at present – is more serious than our native shield bugs, which do negligible harm to runner beans.
Black bean aphid
Sap-sucking aphids will disfigure plants and cause stunting to leaves and stems.
Remedy
In the case of broad beans, pinch out infested tips. On other beans, catch populations when small and squash.
Slugs and snails
These feed on the young seedlings and you'll see the tell tale slime trail on the soil around your crop, as well as on the leaves.
Remedy
There are many ways to control slugs and snails, including beer traps, sawdust or eggshell barriers, copper tape and biocontrols.
No/ very few beans
This is one of the most common problems of bean growing and is usually caused by lack of moisture and/or poor pollination by insects.
Remedy
Plant or sow beans into soil that has had plenty of organic matter, such as well-rotted manure added the previous autumn, as this will aid moisture and nutrient retention around the roots. Plant in a sheltered site as this will encourage bees to visit and pollinate the plants.
Rust
A common fungal disease of many plants that can be recognised by orange, yellow or black spots or blisters that form on leaves, along with pale and distorted stems. Leaves can fall and in severe cases, plants will eventually die.
Remedy
Dig up badly infected plants and dispose of to prevent the spores spreading to other plants. Carefully check plants before buying to ensure they are healthy and show no signs of disease.
Recipes
Nigel Slater recommends serving runner beans with lemon and garlic crumbs, as a lovely side dish for grilled fish.

How to Grow Runner Beans
, written by Ann Marie Hendry
We all know that beans are a musical fruit, or good for your heart, depending on which version of the rhyme you learned when you were a nipper, but in the UK at least no vegetable garden or allotment plot is complete without a wigwam foaming with scarlet-flowered runner beans.
The reason? Well, not only do they make a delectable vegetable, they are drop-dead gorgeous too.
Sowing and Growing Runner Beans
Runner beans - a type of pole bean - were traditionally planted atop filled-in trenches dug the previous autumn and stocked with well-rotted manure or shredded newspaper. Kitchen waste will work too, because the main reason for doing this is to provide a deep, moist root run that will help runner beans to resist drought. Drought is a major enemy of beans, so avoid this at all costs.
Start sowing runner beans in spring and keep sowing every couple of weeks until early summer to spread out the harvest. Exactly when to sow will depend on your climate, so check out our Garden Planner for customized advice. The earliest seeds can be sown in modules or seed trays in a greenhouse, tunnel or on a sunny windowsill for transplanting later on.
Runner beans dislike cold soil, so wait until the soil has warmed to at least 10ºC (50ºF) before planting them out. You can warm soil a week or so in advance of sowing or planting using cold frames, cloches, row cover tunnels or even just sheets of plastic.
Later sowings can be made directly where they are to grow, but beware of hungry slugs and make sure to protect seedlings from wind damage. Covering them with a cloche (even a recycled plastic bottle will do) will provide all the shelter they need until they establish.
In cool or windy locations you can protect plants and boost pod production by growing them to maturity in a greenhouse or tunnel – just make sure to ‘stop’ the plants, or pinch out the growing tips, when they near the roof.
While closely-related French beans are self-pollinating, runners need help from pollinators such as bees and hummingbirds, so yields will be hampered by a wet, cold summer when insects are unlikely to be flying. A dry summer is bad news too, so make sure to water during rainless spells and mulch to preserve that moisture.
Beans are usually pretty trouble-free, but keep an eye out for black bean aphids infesting the growing tips. If this happens, clip off the tips and dispose of them.
Supporting Runner Beans
Get supports in place before planting your runners. Any frames or trellis need to be sturdy enough to support these lanky beans, which grow to well in excess of 2m (6.5 feet) tall and which will become extremely heavy when laden with pods. Netting is often used along with canes or poles to allow the vines to clamber about freely.
Bean wigwams look just as attractive in the flower garden as they do in the vegetable garden. Runner beans were originally grown purely as ornamental plants, so you can find exciting flower color choices such as ‘Scarlet Runner’ or the ravishing red-lipped white flowers of ‘Painted Lady’.
You may need to tie young plants in to their supports initially, but once they’ve got a grip they should manage on their own. If they’re catching the wind they may need to be tied in at intervals.
When the plants reach the top of their supports, pinch out their growing tips to help divert energy into flower and pod production – and to avoid the plants turning into a jungle of tangled stems and foliage.
Such tall, leafy plants will cast shade, so plan your garden to include shade-loving crops behind your towering beanstalks.
Harvesting Runner Beans
Keeping up with weeding, watering and mulching is important while the beans are growing. Apply an occasional liquid feed too. Harvesting will commence around midsummer and continue until the first frosts. Runner beans will crop slightly later than French beans, so for variety and to extend the season it can be worth growing both.
Pick your beans while they’re still quite small to avoid any stringiness, though having said that modern cultivars are usually bred to be stringless. Pick at least every other day, because you’ll be astounded at how rapidly a bean pod can grow – they seem to go from flat to fat in the blink of an eye!
If you’re going to be away during the summer, invite friends and neighbors to help themselves to your beans to encourage continued cropping for when you return. Alternatively you could use the break as an opportunity to switch from producing fresh pods to maturing beans for drying. Gluts of the whole fresh pods can be chopped, blanched if you wish (I never do, I can’t tell the difference!) then frozen.

How to grow green beans - Summer advice
Green, French, asparagus, green beans ... as soon as our gardeners do not call this tender beans. Many of us adore this mega-healthy vegetable, grow it easily, naturally and with pleasure, managing to collect unprecedented harvests from several bushes. And someone does not give beans at all. It seems that they are planting and watering, but as a result, disappointment: again something has grown that does not look a bit like green beans.
How to grow green beans without complaining about the harvest? We reveal all the secrets of growing truly wonderful pods! nine0003
String beans
String beans come in several varieties: green, yellow, purple, white with purple streaks, sometimes even with pink pods. But for us, gardeners, it is much more important that green beans are divided into curly and bush.
Both bush and climbing beans have their advantages and disadvantages. So, for example, bush beans are less thermophilic than curly beans, do not require support and, as a rule, give the crop together (it is harvested in 2-3 doses). But curly beans give more pods, due to constant growth, it grows up, so it can take free space between other plants, it can be planted along the fence (or instead of it) as a hedge. nine0003
We advise you to plant several plants of each type as a test in order to decide which one is easier for you to take care of, which one will be more productive, etc. The only thing is that for the northern regions it is better to choose early-ripening varieties that begin to bear fruit two months after planting. Summer residents of the southern regions can afford late varieties.
Planting green beans
Green beans are heat-loving crops, so they are planted quite late when the ground warms up well and frosts are no longer expected. Usually planting is done in late May - early June. nine0003
String bean is a thermophilic crop, so it is best grown in sandy soils. This is especially true of the northern regions, where in cold summers, green beans may not produce pods at all. So we add sand to the beds, place them in a well-heated place or build a warm bed for the beans.
String beans are a heat-loving crop, so a couple of weeks before planting, it is recommended to cover the bed with foil to warm the ground. If you want to plant your beans in a warm bed (which is exactly what you need), soak them with an EM solution and then cover with foil. In well-warmed soil, beans will sprout earlier. nine0003
String bean seeds must be soaked before planting. At least - for two hours, as a maximum - before the appearance of seedlings. Beans planted with germinated seeds will sprout quickly and amicably.
The bed is laid out according to the scheme: 8-10 centimeters between bushes, 30-40 centimeters between rows. For curly beans, you can increase these distances and immediately put the supports. Green beans are planted two seeds in one hole, then to choose the strongest plant. The optimum sowing depth is 3 cm. nine0003
After planting, the bed is watered and mulched with humus, straw or grass. Do not be afraid to mulch the beans (many worry that the soil warms up more slowly under the mulch), we warmed up the bed well beforehand, and the mulch perfectly retains the moisture vital for seed germination. If you are not a fan of mulching, you need to ensure that the bed is always damp (but not overflowing).
In two weeks (maybe earlier) the first shoots of green beans will appear. nine0003
String bean care
String beans or green beans do not require special care. It is not even necessary to feed it, especially when grown in warm beds under organic mulch. The only thing that this plant desperately needs is heat. We repeat and remember once again: green beans are a thermophilic culture. It grows best at a temperature of + 20-25 ° C.
So, as the seedlings grow, we choose the strongest ones, and pinch their neighbors under the root (no need to pull out, why disturb the root system once again?). For those who do not want to mulch, it would be nice to spud the beans when the bushes grow up to ten centimeters in order to create all the conditions for the development of the roots. nine0003
In the future, we are required to provide the plants with moisture either through regular heavy watering, or through mulching and watering during especially hot periods. A couple of times during the season, you can water the beans with infusion of ash.
When the curly beans reach two meters in height, boldly pinch the top to stop the growth of the stem and direct all the juices to fruit set.
Harvest of green beans
Harvesting of green beans must never be delayed. As soon as the beans are finally formed and ripened in the pods, the bush will stop developing. When the plants are "sure" that they have produced seeds for procreation, they stop growing. Our task is to track the appearance of pods. Yeah, we started ... in a week we are harvesting the first crop. The more often you cut the pods, the more ovaries the bush will give out. Therefore, after 4-6 days, we again examine the plants - most likely, we again have something to collect. nine0003
By the way, the best time to harvest green beans is on a cool morning. This way the blades stay fresh longer. String beans are usually stored frozen. Immediately after harvest, the pods are cut into several pieces, placed in bags and placed in the freezer until winter.
When the freezer is full and the lobio for lunch is completely tired, you can leave the last bean pods hanging until full maturity and take seeds from them for the next year.
We wish you success and great harvests! nine0003
Growing green beans. Planting, garter, harvest
Who is used to calling such beans - string, asparagus, green. You will not find it in every garden, although it is very tasty and healthy, besides, the bean plant saturates the soil with nitrogen. That is why everything that is planted in the place where the beans grew grows well.
This plant is quite unpretentious, grows well on any soil. You only need to meet 2 conditions: provide her with one of the sunniest places on the site and water it in a timely manner. If you have only a shaded place left for the beans, then at least make the bed higher so that there is no stagnation of moisture. nine0065 Naturally, any plant grows better on fertile soils and beans are no exception, but this is not critical. The only top dressing we use for beans is ash infusion.

Planting beans
Asparagus beans are afraid of even short-term subzero temperatures, so they should be planted in the middle lane and northern regions no earlier than the end of May-beginning of June, when the threat of return frosts has passed.
Beans are planted in the same way as beans or peas. That is, you can use dry seeds, or you can pre-soak them or even germinate them.To do this, the seeds are poured with warm water (25-30 degrees) for several hours and then planted in the garden. Make furrows at a distance of about 30 cm from each other. The seeding depth is 2-4 cm. The distance in the row between plants is about 15-20 cm. Until sprouts appear, the bed must be kept moist. You can even cover it with foil. nine0065

Growing seedlings of beans
To get a harvest a little earlier, it is necessary to grow seedlings. Planting for seedlings begins a month before planting in the ground, that is, for the middle lane this is the end of April. Bean seeds are pre-soaked for several hours or a day. During the day, sprouts are usually already visible and bad seeds can be easily rejected. Beans are planted in separate cups, deepening into the ground by 2-3 cm. That is, timely watering and a well-lit place. nine0065 Seedlings are planted in the ground when the temperature is above zero both day and night, usually this is the beginning of June.
String beans grow best when the soil is warm, so take your time to mulch the plants.

Ways of growing green beans
There are 2 types of green beans: bush and climbing. Bush beans are easier to grow, they are undersized, usually a bush 30-40 cm high. They are planted both on separate beds and among other crops. Very often you can see bean bushes among potato plantings, and even more often along the perimeter of a potato field. nine0003
Curly beans are another matter. For it, it is necessary to build supports along which it will grow upwards. Usually these are trellises, as for cucumbers, or all kinds of tall structures such as a hut, pyramids, etc. Some gardeners grow curly green beans along a grid, for which it clings to itself and stretches up. Curly beans tie pods along their entire height (and this is more than 2 meters), so its yield is higher.
String beans begin to bear fruit 2 months after germination. nine0003Both beans are harvested not at once, but as the pods grow, that is, several times during the summer.
They are removed in milky ripeness, when the formed grains are still invisible in the pods. At this stage, green beans are tastiest and tender, with no coarse fibers. A variety of main dishes, salads are prepared with it, and they are also preserved for the winter. Many people prefer to freeze beans for the winter, for this they usually cut the pods into 3-4 parts and arrange them in portions in bags. Currently, frozen green beans are sold in any supermarket, but their own is much tastier and more tender. nine0003

String bean seeds
For seeds, a plant is usually left, from which the pods are not removed. The pods fully mature on the bush. Then you can collect these pods and dry them and store them in a linen bag, or you can cut the whole plant and hang it somewhere in the barn.
Why cut the plant instead of uprooting it? It is important! On the roots of beans (as well as other legumes) a special type of beneficial nodule bacteria is formed that can saturate the soil with nitrogen taken from the air. Under good conditions, up to 700 nodules are formed on the roots of 1 plant! As a result, enriched soil remains after harvesting the beans. And the roots and residue of the plant remaining in the soil will be food for earthworms. nine0003

Varieties of string beans
There are varieties in which only tender shoulder blades (pods) are used for food, as well as shelling varieties, in which only grains from the pods are used as food.
The most popular varieties are Saksa 615, Zolotaya Gora, Triumph Sakharny, Dialog, Vestochka, Sakharny 116.
