How to Grow Beans in Pots
Beans are fast, generous and easy in a pot, with bush types needing no support at all.
Beans are one of the most productive crops you can grow in a container for the space they take. They grow fast from seed sown straight into the pot, fix their own nitrogen, and crop heavily. Bush beans need no support, while climbers turn a pot into a leafy, productive screen.
Bush or climbing?
Bush (dwarf) beans grow knee-high, need no support, and crop in a quick flush, ideal for a smaller pot. Climbing beans need a tall support but crop over a much longer period and use vertical space, giving more beans per pot. Choose bush for simplicity and speed, climbing for a bigger, longer harvest.
Pot, mix and support
Use a pot at least 25 to 30 cm deep, larger for climbers, with good drainage. A trough suits a row of bush beans. Fill with a quality potting mix and compost. For climbers, put a sturdy teepee, trellis or stakes in at sowing time, they grow fast and will want it within days of emerging.
Sowing and care
Sow bean seed straight into the pot once the weather is warm, about 3 cm deep, beans dislike cold soil and transplanting. Keep the mix evenly moist, especially once flowering and podding, as dry spells reduce the crop. Beans make their own nitrogen, so go easy on nitrogen feeds, which give leaves at the expense of pods. A higher-potassium feed once flowering helps podding.
Harvest
Bush beans are usually ready in eight to ten weeks, climbers a little longer but over a longer season. Pick while the pods are young, slim and snap cleanly, before the seeds bulge through. A few pots of climbing beans can keep a household in beans through the warm months.

Can you grow beans in pots?
Yes, beans are one of the best value container crops. Bush types need no support and crop fast, while climbing types use vertical space for a bigger, longer harvest. Both grow easily from seed sown into the pot.
What size pot do beans need?
At least 25 to 30 cm deep with good drainage, and larger for climbing beans. A long trough suits a row of bush beans. Climbers also need a tall sturdy support put in at sowing time.
Do beans in pots need support?
Bush or dwarf beans do not, they stay knee-high. Climbing beans do, and need a tall teepee, trellis or stakes installed when you sow, because they grow fast and reach for support within days of emerging.
How often do you water beans in containers?
Keep the mix evenly moist, especially once the plants are flowering and podding, when dry spells reduce the crop. Containers dry quickly, so check daily in warm weather and mulch the surface to slow drying.
Why are my potted beans all leaves and no pods?
Usually too much nitrogen. Beans fix their own nitrogen, so extra nitrogen fertiliser drives leafy growth instead of pods. Use a higher-potassium feed once flowering, ensure full sun, and keep picking to encourage more pods.
