Borlotto Nano is a compact, dwarf variety of borlotti bean (also called cranberry bean) that produces striking deep red and cream-colored mottled pods and seeds. This bush bean variety is ideal for small gardens, containers, and space-limited growing areas while maintaining the classic nutty flavor of full-size borlotti beans. The plants typically reach only 12-18 inches tall, making them perfect for urban gardeners and intensive plantings.

Growth Stages

1

Seedling

1-2 weeks

Emerging cotyledons appear above soil; first true leaves develop within 7-10 days

Keep soil evenly moist but not waterlogged. Provide bright light and warmth (65-75°F). Thin seedlings if starting indoors.

2

Vegetative Growth

2-3 weeks

Compact bushy plant develops with 4-6 true leaves; stems thicken and plant reaches 6-10 inches

Maintain consistent moisture. Weed regularly to reduce competition. Add mulch at 2 inches to conserve moisture and suppress weeds.

3

Flowering

1-2 weeks

Small white or pale purple flowers bloom along the stems; plant height reaches 12-18 inches

Maintain regular watering schedule. Do not overwater or over-fertilize, which can delay pod set. Avoid overhead watering.

4

Pod Development

2-3 weeks

Green pods emerge and grow 4-5 inches long; distinctive mottled red and cream coloring begins appearing

Water regularly but allow soil to dry slightly between waterings. Do not disturb plants when picking pods. Monitor for pests.

5

Harvest/Maturity

1-2 weeks for shell stage; 3+ weeks for full drying

Pods become fully colored with deep red mottling on cream background; seeds inside become visible and hard

Harvest regularly for fresh shelled beans, or allow pods to dry on plant for dried beans. Plant will continue producing until frost.

Common Pests

  • Hand-pick beetles and yellow egg clusters. Use row covers on young plants. Apply neem oil or spinosad if infestation is severe.

  • Hand-pick yellow egg clusters from leaf undersides. Remove affected leaves. Apply spinosad, neem oil, or pyrethrin. Encourage parasitic wasps.

  • Increase humidity and mist plants regularly. Spray with strong water jet to dislodge. Use miticides only if severe.

  • Improve air circulation. Water at soil level only. Remove infected leaves. Use sulfur dust if needed. Avoid handling wet plants.

  • Ensure adequate spacing for airflow. Avoid overhead watering. Apply sulfur spray or baking soda solution early in disease progression.
