Supporting Runner Beans
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.
Can you stop runner beans growing too high?
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.
How deep do runner beans need to be planted?
Sow runner beans direct once the last frost has passed and the soil has begun to warm up. If starting off under cover, plant one seed per pot around an inch deep. Runner beans grow long roots, so use tall pots or root trainers (opens in new tab), which will allow the seedlings to thrive.

Should you pinch out runner beans?
When your runner bean plants reach the tops of the canes, pinch out the growing tip of each one to encourage bushier growth. Beans are thirsty plants so water regularly, especially when in flower, and mulch the soil surface around the roots, to lock in moisture.
Should I top my beans?
Pinch off the tops of pole bean vines when they reach the top of the support. This will force them to put energy into producing more pods instead. In high heat, use row covers over young plants; hot weather can cause blossoms to drop from plants, reducing the harvest.
When should I cut down runner beans?
At the end of the summer, cut down the old stems and compost them. Leave the roots in the ground as they can have useful nitrogen nodules which will fertilise the ground for future crops.
How do you keep beans from climbing?
As most beans are climbers (unless you go for the dwarf or “bush beans”), you need to think about that before you whack them in. They need support as they get up to about 2m high. A wire trellis, fence lines, frames or similar can be used to prop them up.
Should you leave runner bean roots in the ground?
Once your harvest is over then we recommend cutting the stalks at the base, leaving the roots in the ground to rot. Then simply pop the foliage in the compost heap if you have one, or just let them decompose on the surface of the soil if not.
Is blood fish and bone good for runner beans?

Do you tie runner beans to Canes?
Plant runner beans
For a wigwam push the canes firmly into the ground in a circle and tie them together near the top. For rows, the canes should be about 40cm apart with the rows 75cm apart. After the risk of frost has passed plant one runner bean at the base of each cane and water well.
How tall should bean poles be?
6 to 8 feet
When using poles as pole bean supports, you’ll want the pole to be 6 to 8 feet (2-2.5 m.) tall. The pole should be rough to help the bean grow up the pole. When planting pole beans to grow on a pole, plant them in hills and place the pole in the center of the planting.
What’s the difference between climbing beans and runner beans?

How often should I water my runner beans?
Runner bean plants need lots of water, one look at the amount of foliage per plant will tell you that. If the weather becomes dry water them once a week with lots and lots of water. Weed around the base of the plant to reduce competition from weeds.
Why are there no beans on my runner beans?
Q Why aren’t my runner beans flowering? A Sometimes you just need to be patient, as runner beans often take quite a while to start flowering. Spells of hot, dry weather can cause the buds to drop off, as can a lack of pollinators. Birds sometimes pick off the buds, too.
