Description

(Phaseolus vulgaris) Pole bean. Bright emerald green dry beans are delicious in soups or eaten as a green bean. 5- to 6- inch pods yield kidney-shaped beans in the most dazzling gemstone colors of the plant kingdom. Drought and heat tolerant, the bean originated in Kenya where its name, Mbombo, has an association to a Creator God of the same name. The bean is thought to be a sign of prosperity and brings good fertility to the soil. Great for a trellis or small fence. This pole to semi-pole bean is brought to us by Stephen Smith from his colorful bean collection.

Growing Tips: Mbombo Green beans are drought and heat tolerant. To ensure optimal growth, plant these beans in full sun and well-draining soil. Adding compost or aged manure before planting can improve soil fertility and water retention.

When to Grow

Plant Mbombo Green beans after the last frost when the soil temperature is consistently above 65 F. The ideal temperature for growth is 70-80 F. They take about 50-60 days to mature, which is quick enough for short growing seasons. This is a pole to semi-pole bean, so a single sowing keeps bearing over a long season and there is no need to resow every couple of weeks. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Soaking the seeds for 2 to 3 hours before planting can enhance germination but is optional. Sow the seeds about 1/2 to 1 inch deep. Ensure the soil is warm and keep it consistently moist until the seedlings emerge. Mbombo Green beans have long vines and need support, so use a trellis or small fence to help them grow vertically​.

How to Grow

Sprouts usually appear in 5 to 8 days. Once the seedlings have emerged, thin them to about 6 to 10 inches apart. Water the plants regularly, especially during dry spells, but avoid over-watering. Beans fix their own nitrogen, so excessive fertilization is unnecessary. Regular weeding and mulching can help retain soil moisture and prevent weed growth​​. Harvest frequently to keep plants productive.

How to Save Seeds

  • Common beans do not easily cross pollinate and can be grown close to one another, making them the ideal seed-saving project for beginners.
  • Save seeds from the best-looking, best-tasting, and most vigorous beans.
  • Leave pods on the plant to dry. Pull the plants and shake them vigorously into a bag to release the beans from the pods (same as you would for using them as dried beans).
  • Store in a cool, dry place for the winter (a glass jar in the refrigerator works well!).

FAQ

Do Mbombo Green beans need support?

Yes, they are a pole variety and require support such as a trellis or a small fence to grow properly.

How often should I plant new seeds for continuous harvest?

You do not need to. Mbombo Green is a pole to semi-pole bean, so one sowing bears over a long season rather than all at once the way a bush bean does. If you do want a second planting, make it early enough that at least 50-60 frost-free days remain, since these beans are not frost-hardy.

Are Mbombo Green beans frost-hardy?

No, they are not frost-hardy and should be planted after the last frost date in your area.
