FAQs

What is the best time to sow Runner Bean ‘White Emergo’ seeds?

You can sow seeds indoors from mid-April or directly outdoors from late May to July.

What kind of soil does this variety prefer?

It prefers rich, well-drained soil. Avoid planting in freshly manured soil, as this can lead to excessive foliage growth.

How tall can these runner beans grow?

The plants are vigorous and can reach a height of up to 300cm (approximately 10 feet).

Do I need to provide support for the plants?

Yes, these runner beans are climbers and require sturdy support such as canes, strings, or netting to grow effectively.

When is the best time to harvest the beans?

For the best flavor and tenderness, harvest the beans when they are young.

What does 'RHS AGM winner' mean?

RHS AGM stands for Royal Horticultural Society Award of Garden Merit, indicating that the variety has been recognized for its outstanding garden performance.

What are the ideal germination conditions?

Seeds germinate best in a propagator or sealed container at a consistent temperature of 18-20°C (64-68°F).

Troubleshooting

Seeds not germinating

Ensure consistent temperature (18-20°C) and moisture. Check that the seed-sowing compost is fresh and suitable for germination.

Poor bean production

Verify the plant is receiving adequate sunlight and water. Avoid planting in freshly manured soil. Ensure regular harvesting of young pods to encourage more growth.

Leggy seedlings

Provide cooler conditions once germinated and ensure adequate light. Avoid overly warm temperatures after germination.

Plants damaged by wind

Ensure sturdy support structures are in place before planting and that the location is as sheltered as possible.

Setup, Compatibility & Care

Indoor Sowing (from mid-April):

  1. Plant seeds 5cm (2") deep in 7.5cm (3") pots filled with seed-sowing compost.
  2. Place pots in a propagator or sealed container at 18-20°C (64-68°F) for germination (7-10 days).
  3. Grow seedlings in cooler conditions until all risk of frost has passed.
  4. Gradually acclimatize seedlings to outdoor conditions over 7-10 days before planting.

Outdoor Sowing (late May to July):

  1. Sow seeds directly into rich, well-drained soil.
  2. Plant seeds 5cm (2") deep, spaced 30cm (12") apart.
  3. If planting in rows, space them 1.5m (5') apart. For wigwam structures, plant around the base.
  4. Ensure supports (canes, strings, netting) are in place at planting time.

Planting Location:

  • Full sun or partial shade is ideal.
  • Protect plants from strong winds.
  • Avoid using freshly manured soil, as it can encourage foliage growth over bean production.

Care:

  • Provide adequate support as the plant grows (up to 300cm height).
  • Water regularly, especially during dry spells.
  • Pick beans regularly when young and tender to encourage further production.
