When to Grow

Plant Chinese Red Noodle long beans after the danger of frost has passed and the soil temperature is consistently above 60 F, ideally between 75-95 F. In cooler climates, starting seeds indoors 3-6 weeks before the last frost can give the plants a head start​.

How to Sow and Plant

Preparation: Choose a sunny spot with well-draining soil, ideally with a pH between 6.0 and 7.0. Enrich the soil with compost or aged manure. Soak seeds overnight before planting.

Planting: Sow seeds 1/2 to 1 inch deep and space plants 6 inches apart. If using a trellis, space rows about 18 inches apart. Trellises are essential as these beans are vigorous climbers.

Watering: Keep the soil moderately moist until germination, then maintain consistent moisture, especially during flowering and pod formation. Mulch around the plants to help retain moisture and suppress weeds.

How to Grow

Full sun is essential, with 8-12 hours of direct sunlight daily. Provide a sturdy trellis or poles for the vines to climb, which helps maximize air circulation and sun exposure. Use a balanced, slow-release fertilizer at planting. Avoid excessive nitrogen, which can lead to more foliage and less fruit. Switch to a fertilizer higher in potassium and phosphorus as the plants begin to flower​.

How to Save Seeds

  • This self-pollinating annual in the legume family will not readily cross with other nearby varieties, so a distance of 10-20 feet between other cowpea or long bean varieties is sufficient to ensure pure seed.
  • It is super easy to save seed; just allow pods to dry and wait for seeds to become dry and hard.
  • You should not be able to dent the seed with your thumbnail.
  • Store seeds in a cool, dark, dry place.

FAQ

Can I grow Chinese Red Noodle long beans in containers?

While it's possible, it is not the best choice because of their vigorous growth and need for substantial support. If you choose to use containers, ensure they are large and deep enough to support the plant and provide a sturdy trellis.

What pests should I watch out for?

Common pests include aphids and spider mites. Regular monitoring and natural predators like ladybugs can help manage these pests. Organic treatments such as neem oil or insecticidal soap are also effective.

How do I know when to harvest Chinese Red Noodle long beans?

Harvest the beans when they are about the thickness of a pencil and 12-18 inches long. Overripe pods will become tough and stringy. Frequent harvesting encourages more production.

How can I store long beans after harvesting?

Store fresh beans in a plastic bag in the refrigerator for up to a week. For longer storage, blanch and freeze the beans to preserve their color and flavor.
