🗓️ When to plant

In cool climates, sow in early spring after the last frost or in autumn 6–8 weeks before the first frost. In mild climates, sow in mid-autumn for winter harvest.

🌰 How to plant

1. Soak seeds in water for 12 hours before planting to speed germination.
2. Sow seeds 5 cm (2 in) deep directly into garden soil or large pots.
3. Space seeds 20–25 cm (8–10 in) apart in full sun.
4. Water gently after sowing and keep soil moist until seedlings emerge (10–14 days).

💧 Care

• Pinch off the top 10 cm (4 in) of growing shoots when flowers first appear to reduce pest damage and encourage pod development.
• Provide support with stakes or trellising if plants exceed 60 cm (2 ft) in height.
• Mulch around plants to retain moisture and suppress weeds.
• No fertilizer needed if soil is rich; excess nitrogen encourages leafy growth over pods.

🧺 Harvest

Pick pods when they feel full but before beans inside harden; they're most tender when 5–8 cm (2–3 in) long. Harvest regularly to encourage continuous production, or leave pods to mature fully for dried beans.

🐛 Common problems

Chocolate Spot (fungal disease): Improve air circulation by spacing plants adequately and avoid overhead watering; remove affected leaves promptly.

Black Aphids: Pinch off infested shoot tips, spray with neem oil, or introduce ladybugs for natural control.

Root Rot (in wet soil): Ensure well-draining soil and avoid overwatering; plant in raised beds if drainage is poor.
