FAQs
When is the best time to sow 'Polestar' runner bean seeds?
You can sow seeds from March onwards, either indoors or directly into the ground after the risk of frost has passed. A second sowing in June can extend the harvest into autumn.
How tall do these beans grow?
As a runner bean variety, 'Polestar' is a vigorous climber and can grow to significant heights, typically requiring supports of 1.8 to 2.5 meters (6 to 8 feet).
Can I grow these in containers?
Yes, 'Polestar' runner beans are well-suited for container growing, provided you use a large pot (at least 30cm or 12 inches deep) and a sturdy support structure.
How often should I water them?
Water regularly, especially during dry spells and when the plants are flowering and setting pods. Aim to keep the soil consistently moist but not waterlogged.
Are the flowers edible?
Yes, the salmon-coloured flowers of the 'Polestar' runner bean are edible and can be used in salads or as a garnish.
How long does it take for the beans to mature after flowering?
Pod development is relatively quick after flowering, with young, tender beans ready to harvest in approximately 6-8 weeks from sowing, depending on growing conditions.
Can I save seeds from this variety?
While runner beans can be saved, 'Polestar' is a specific cultivar. Saving seeds may result in variation in subsequent years. For consistent results, it's best to purchase new seeds annually.
Troubleshooting
Seeds fail to germinate
Ensure soil is warm enough, seeds are planted at the correct depth, and kept consistently moist. Use fresh seed if germination is poor.
Plants are leggy and weak
Provide adequate sunlight and ensure good soil fertility. Check that support structures are in place and accessible for climbing.
Few or no beans are forming
Ensure adequate pollination (though 'Polestar' is good in this regard), consistent watering, and sufficient nutrients. Avoid excessive nitrogen, which can promote leaf growth over flowering/fruiting.
Flowers drop without forming pods
This can be due to stress from extreme temperatures (too hot or too cold), inconsistent watering, or nutrient imbalances. Ensure stable growing conditions.

Setup, Compatibility & Care
Sowing:
- Sow seeds indoors or directly outdoors after the last frost, typically from March onwards.
- Ensure seeds are planted about 2-3cm (1 inch) deep in well-draining soil.
- Provide support structures such as canes, netting, or a trellis before sowing, as these beans are vigorous climbers.
Growing Conditions:

- Soil: Prefers fertile, well-drained soil. Amending with compost or well-rotted manure is beneficial.
- Watering: Water regularly, especially during dry periods, to ensure consistent pod development.
- Support: Crucial for the plant's vertical growth. Ensure supports are sturdy.
Care:
- Pest Monitoring: Keep an eye out for common bean pests like slugs and blackfly. Address any infestations promptly.
- Harvesting: Pick beans regularly when young and tender to encourage further production. Edible flowers can be picked as needed.
- End of Season: Remove plants after the first frost.
