Establishment
6-8 weeksYoung plant developing roots and initial leaf growth. Corm or pup produces first leaves.
Keep soil consistently moist but not waterlogged. Protect from strong winds. Begin light fertilizing after 4-6 weeks. Mulch around base.
Vegetative Growth
4-6 monthsPlant rapidly produces large leaves and expands rhizome system. Can reach 6-12 feet tall. Side shoots (pups) emerge from base.
Feed every 4-6 weeks with balanced fertilizer high in potassium. Maintain consistent moisture. Remove competing pups if single stem desired. Stake if in windy area.
Flowering & Fruit Set
2-3 monthsInflorescence emerges from leaf whorl, producing distinctive purple or reddish flowering bracts. Flowers open and small green fruitlets form in bunches (hands).
Increase potassium and phosphorus fertilization. Ensure consistent watering. Provide wind protection as heavy fruit develops. Remove male bracts if desired to redirect energy to fruit.
Fruit Development & Maturation
2-3 monthsBanana bunches (stems) enlarge and fruit fingers grow to full size. Initially green, may show slight color change indicating maturity. Fingers become plumper and crowns round out.
Support developing fruit bunches with slings or padding if weight is excessive. Continue regular fertilization. Reduce watering slightly as fruit approaches maturity. Watch for pest damage.
Harvest Ready
Variable; typically ready 8-10 months after floweringFruit reaches full size and develops slight yellow-green color or angularity changes. Plant may yellow slightly; stem strength remains firm.
Harvest when fruit is full-sized but still mostly green (for cooking) or when slight yellowing shows ripeness preference. Cut entire bunch at once. Prepare for next fruiting cycle.

Cooked plantains provide filling carbohydrates and are less sweet than dessert bananas. [source]
Nutritional Staple
CulinaryPlantains are rich in resistant starch, potassium, vitamin B6, and vitamin C. They provide sustained energy and are gluten-free, making them valuable in diverse global food traditions. [source]
Traditional Medicine
MedicinalIn traditional medicine systems, plantain fruit and leaves have been used to support digestive health and provide anti-inflammatory benefits. The fruit's high fiber content supports gut health. [source]
Starch & Flour

Harvest Tips
Cut entire bunch when fruit reaches full size; typically 8-10 months after flowering. For cooking (green stage), harvest when fruit is mostly green with slight rounding of fingers. For riper eating, allow slight yellowing. Use a sharp machete or saw to cut the stem. Plantains are less perishable than dessert bananas and store 2-4 weeks at room temperature. The plant will die back after fruiting; cut the stalk to ground level to encourage new shoots from the rhizome.
