Black Beauty No.1 is a high‑quality F1 hybrid yardlong bean variety. These yardlong bean seeds develop vigorous climbing vines, bearing plenty of extra‑long, slender, uniform dark‑green pods. Pods stay tender and crisp, not easy to become fibrous. This hybrid owns strong disease resistance and stable high‑yield performance, well‑suited for warm‑season open‑field cultivation. Full‑sun planting boosts vine growth and pod output. Set up trellis supports for vines to climb upward, improving air circulation. Keep observing for common bean pests and diseases in the whole growing period. Maintain even soil moisture, avoid waterlogging. Apply balanced fertilizer before blooming, and supplement potassium‑rich fertilizer during pod‑setting phase to gain abundant tender pods.
Planting Instructions Soil Preparation Select a full‑sun location with good drainage. Mix sufficient well‑rotted organic compost into fertile loose loamy soil. Stay away from low‑lying water‑logged plots.
Seed Pre‑treatment Select plump complete seeds. Soak seeds in warm water for 4‑6 hours before sowing to raise germination rate. Cold stratification is unnecessary.
Sowing Method Sow after frost disappears and soil temperature rises. Put 2‑3 seeds in each hole, cover with 2‑3 cm fine soil. Plant spacing 30‑40 cm, row spacing 60‑70 cm. Keep 1‑2 robust seedlings per hole after thinning. Build trellises for climbing growth.
Germination Condition Optimal germination temperature:22‑30°C. Seedlings sprout within 5‑8 days. Keep soil moderately moist, prevent root soaking.
Daily Maintenance Keep stable soil moisture. Apply balanced fertilizer pre‑bloom, switch to potassium‑rich fertilizer when pods begin to form. Clear weeds timely. Guard against aphids and pod borers. Harvest young tender pods before they turn tough and fibrous for best flavor.
