Growth Stages

1

Seedling

2-3 weeks

Cotyledons emerge within 7-10 days; first true leaves appear shortly after. Plants are tender and vulnerable to cool temperatures.

Maintain warm soil temperature (70-80°F minimum). Water gently to avoid disturbing seedlings. Provide protection from wind and cool nights.

2

Vegetative Growth

3-4 weeks

Vigorous climbing vine develops with multiple stems, compound leaves, and tendrils. Plant reaches 3-4 feet tall during this phase.

Install sturdy trellises or support structures early. Provide balanced fertilizer every 3-4 weeks. Maintain consistent moisture. Remove any weak or damaged growth.

3

Flowering

2-3 weeks

Small, delicate white to pale yellow flowers appear in clusters along the vine. Flowers are self-pollinating but benefit from bee activity.

Continue consistent watering and light fertilizing. Avoid excessive nitrogen which promotes foliage at the expense of flowers. Ensure adequate air circulation to prevent fungal issues.

4

Pod Development & Fruiting

3-4 weeks

Speckled calico pods form and elongate to 3-4 inches. Pods gradually fill with beans, developing the characteristic burgundy and cream coloration.

Maintain steady moisture, especially during pod fill. Reduce nitrogen feeding to encourage pod development. Monitor for pests and diseases. Mulch around base to retain moisture.

5

Harvest

Ongoing, 2-3 weeks of production

Pods mature to full size with pronounced speckled pattern. Beans inside become firm and fully colored. Pods dry slightly and may show cracks.

Harvest pods when full but still tender for fresh use, or allow to mature fully on the vine for dry beans. Check plants every 2-3 days during peak production.

Common Pests

  • Hand-pick beetles and egg clusters daily. Use row covers on young plants. Apply neem oil or spinosad if infestations are severe. Rotate crops yearly.

  • Spray with strong water spray to dislodge. Use insecticidal soap or neem oil. Encourage beneficial insects like ladybugs. Avoid excessive nitrogen fertilizer.

  • Mist foliage regularly to maintain humidity. Spray with miticide or sulfur dust. Encourage natural predators. Remove heavily infested leaves.

  • Ensure good air circulation. Apply sulfur dust or baking soda spray (1 tbsp per gallon water). Remove infected foliage. Avoid overhead watering.

  • Remove infected leaves promptly. Apply copper fungicide preventatively. Improve air circulation. Water at soil level only. Destroy infected plant material.

Harvest Tips

For fresh snap beans, harvest pods when full but still tender and before beans fully mature, typically 70-75 days after planting. For dry beans suitable for storage, allow pods to remain on the vine until they brown and dry completely (85-90 days), then harvest entire pods. Shell dried beans and store in cool, dry conditions. Regular harvesting of tender pods encourages continued production.
