Growth Stages

Seedling

2-3 weeks

Tiny shoots emerge with cotyledons unfurling; first true leaves appear within 1-2 weeks

Keep soil consistently moist but not waterlogged. Protect from birds and cutworms. Provide warmth (70-80°F optimal).

Vegetative

3-4 weeks

Plants develop bushy growth with multiple stems and compound leaves; no flowers yet

Thin seedlings to proper spacing if needed. Mulch around plants to retain moisture. Monitor for pests. No fertilizer needed if soil is adequate.

Flowering

2-3 weeks

Small white or purple flowers appear in clusters along stems; plants are at peak growth

Maintain consistent watering during this critical stage. Avoid overhead irrigation to prevent fungal disease. Support plants if necessary.

Pod Development & Maturation

4-6 weeks

Flowers drop and pods form, gradually filling with developing beans; pods turn brown and dry

Reduce watering frequency to encourage pod maturation and drying. Allow plants to naturally dry in field if weather permits. Watch for late blight or mold.

Harvest Ready

Varies with weather

Pods are completely brown and brittle; beans rattle inside when shaken; foliage may be dead or dying

Pods are ready for harvest when they snap easily. Pull entire plants or pick individual pods. Dry thoroughly before storage to prevent mold.

Common Pests

Hand-pick and destroy yellow egg clusters; use row covers; plant trap crops like tansy nearby; spray neem oil or insecticidal soap if severe
Infests stored beans; use airtight containers; freeze beans for 24 hours before storage; store in cool, dry place
Spray with strong water stream; apply neem oil or insecticidal soap; introduce ladybugs or parasitic wasps
Increase humidity by misting; spray neem oil or horticultural oil; remove heavily infested leaves
Ensure proper spacing for air circulation; avoid overhead watering; remove infected leaves; apply sulfur or copper fungicide if needed

Harvest Tips

Harvest navy beans when pods are completely dry and brown, usually 90-110 days after planting. Pods should be brittle and beans should rattle inside. Pick when plants are dry to avoid spreading diseases. For best results, pull entire plants and hang upside down to dry further in a well-ventilated area. Shell beans by hand or rub dried pods between your hands. Store in airtight containers in a cool, dry place for up to one year.
