Growth Stages

1

Germination

7-10 days

Seeds sprout and cotyledons emerge from soil. First true leaves unfold.

Keep soil consistently moist but not waterlogged. Maintain soil temperature 60-70°F. Thin seedlings if direct seeded.

2

Vegetative Growth

3-4 weeks

Bush plants develop compound leaves, reach 12-18 inches in height. Stems thicken and branch.

Mulch to retain moisture and regulate soil temperature. Monitor for pests. Provide gentle support if needed in windy areas.

3

Flowering

2-3 weeks

Small white or pale purple flowers appear in clusters along stems. Plants are at maximum vegetative size.

Maintain consistent watering without overwatering. Avoid high-nitrogen fertilizer. Begin monitoring for bean beetles and spider mites.

4

Pod Development & Maturation

4-6 weeks

Flowers set pods that elongate and fill with developing beans. Pods transition from green to dark brown/black.

Reduce watering as pods mature. Allow pods to fully dry on the plant if weather permits. Stop watering once pods are dry to prevent mold.

5

Harvest & Curing

2-3 weeks curing

Pods are fully brown and brittle. Seeds rattle inside when shaken. Plants may die back completely.

Pull entire plants or pick individual pods. Cure beans in warm, dry location for 2-3 weeks before storage. Shell beans when completely dry.

Common Pests

  • Hand-pick beetles and egg clusters daily. Use row covers during early growth. Apply spinosad or neem oil if infestation is severe. Encourage natural predators like ground beetles.

  • Spray with strong water spray to dislodge mites. Increase humidity. Apply neem oil or insecticidal soap if populations spike. Avoid over-fertilizing with nitrogen.

  • Use row covers on seedlings. Remove crop residue to reduce overwintering sites. Handpick beetles. Apply kaolin clay spray as preventative.

  • Ensure good air circulation. Avoid wetting foliage. Remove infected leaves immediately. Apply sulfur dust if needed. Choose resistant varieties.

  • Control aphids with neem oil or insecticidal soap. Remove infected plants immediately. Plant in isolation from other beans. Use resistant varieties when possible.

Harvest Tips

Leave pods on plants until they are completely dry and brown (typically late September to October). Pods should rattle when shaken. Harvest on a dry day. Either pick individual pods or pull entire plants and hang to dry in a warm, airy location. Thresh beans from dry pods by hand or in a cloth sack. Store in cool, dry place in sealed containers; properly dried beans keep 1-2 years.

Fun Facts

  • 🌱 Orca beans are a striking example of natural seed coat patterning; the name 'orca' comes from their resemblance to the black and white coloring of killer whales.
  • 🌱 Beans fix nitrogen from the air through symbiotic relationships with soil bacteria, making them excellent for crop rotation and reducing the need for synthetic nitrogen fertilizers.
  • 🌱 Orca beans are an open-pollinated heirloom variety, meaning home gardeners can save seeds from their plants for replanting in future years, preserving the variety.
