Care
Care Requirements
LightBright light to partial sun; morning sun with afternoon shade in hot climates. Acclimate gradually to avoid leaf scorch.
WateringKeep evenly moist in the growing season; do not let the root zone dry out. Reduce slightly in cool weather; avoid waterlogged soil.
SoilRich, well-drained, loamy mix with high organic matter (e.g., compost + pine bark + perlite). Slightly acidic to neutral (pH 5.5–7).
FertilizerHeavy feeder. Apply a balanced or high‑potassium fertilizer every 4–6 weeks in spring–summer; supplement with micronutrients.
HumidityPrefers high humidity (60%+). Increase moisture with regular watering and mulch outdoors; group plants or use a humidifier indoors.
TemperatureBest at 68–90°F (20–32°C). Protect below 45°F (7°C); brief light frosts may defoliate but corm can survive with mulch.
Growth & Life Cycle
HabitClumping, suckering herbaceous perennial banana with an upright inflorescence.
Mature Size6–10 ft tall, 3–6 ft wide clump
Growth RateFast in warm, bright conditions; slows markedly in cool weather.
BloomingErect inflorescence with colorful bracts; blooms once per pseudostem after 10–18 months; fruits are seeded and not typically edible.
DormancyNo true dormancy; growth slows in cool seasons. Pseudostem dies after fruiting; corm overwinters if protected from frost.
Propagation
MethodsDivision of pups (suckers), Seed, Tissue culture
DifficultyModerate
Best SeasonSpring to early summer
Maintenance & Notes
PruningRemove tattered leaves and spent flower stalks. After fruiting, cut the spent pseudostem to the base. Thin excess pups, keeping 1–2 strong offsets to renew the clump.
RepottingRepot every 1–2 years or when rootbound/top-heavy. Step up 2–4 inches in pot diameter; use a sturdy, well-draining container.
Pests & DiseasesWatch for spider mites, aphids, mealybugs, scale, and snails/slugs. Provide airflow to prevent leaf spot; avoid soggy soil to deter root/crown rot.
ToxicityNon-toxic to people and pets; fruits contain hard seeds that can be a choking hazard.
