Vegetative Growth
4-6 monthsRapid leaf emergence and stem thickening; plant grows 6-10 feet tall with broad green leaves
Provide consistent watering and fertilization; apply nitrogen-heavy fertilizer every 4-6 weeks, remove dead leaves, support tall stems if needed
Pre-flowering
2-4 weeksGrowth slows as plant prepares for flowering; stem becomes thicker and more stable
Reduce nitrogen, increase potassium and phosphorus fertilization, ensure adequate water, monitor for pests
Flowering & Fruiting
3-4 monthsPurple male flower bud emerges at crown, then develops into dense bunch of hands with curved, horn-like individual fruits developing
Support heavy fruit bunch with props or ties, reduce watering slightly, continue potassium-rich fertilizer, protect from strong winds
Harvest
Variable; up to 2 weeks for ripening off-plantFruits reach full size (12-14 inches long), change from dark green to yellow-green, and become ready for picking or further ripening
Cut entire bunch when first fruit shows color change, allow to ripen at room temperature, plan for pup (sucker) development for next crop

Harvest Tips
Cut entire bunch when first fruit shows color change (yellow-green), typically 270-365 days after planting. False Horn fruits are best harvested at full mature green stage before yellowing for cooking purposes. For eating fresh, allow to ripen off the plant at room temperature until yellow with some brown spots.
Fun Facts
- 🌱 False Horn is named for its distinctive horn-like curved shape with a false shoulder/bulge below the fruit tip, making it visually distinctive from other plantain cultivars.
- 🌱 Plantains produce 'pups' (suckers) from the base after the mother plant fruits; these can be separated and replanted to create new plants, allowing continuous harvests from the same planting area.
- 🌱 Unlike dessert bananas, plantains are typically harvested and cooked green when starchy and firm, or left to fully ripen yellow-black for sweeter, softer fruits—the same fruit can be used two different ways depending on ripeness.
