Seedling
3-6 monthsSmall tree with emerging spiral leaf clusters and developing root system. Prop roots begin to form.
Keep soil consistently moist but not waterlogged. Provide bright light. Protect from strong winds. Apply balanced fertilizer monthly.
Establishment
6-18 monthsTree develops characteristic prop roots and grows taller with increasing leaf density. Spiral leaf arrangement becomes more pronounced.
Reduce watering frequency as tree becomes established. Support prop roots as they develop. Continue monthly fertilization with balanced formula.
Vegetative Growth
12-24 monthsMature foliage pattern established with long sword-like leaves up to 5 feet long. Tree grows substantially taller with robust prop root system.
Water during dry periods. Apply slow-release fertilizer quarterly. Prune dead leaves and branches as needed. Monitor for pests.
Flowering
Several months (flowers appear seasonally or year-round in ideal conditions)Highly fragrant cream to yellow flowers appear in large, ornate clusters among the foliage. Flowers are arranged in dense inflorescences.
Maintain consistent watering and fertilization. Provide full sun for maximum flowering. Remove any competing dead growth to direct energy to flowers.
Fruiting & Maturity
6-12 months per fruiting cycleDistinctive pineapple-like fruit clusters (keys) develop, each composed of 40-100 individual drupe-like segments. Keys mature to yellow-orange over several months.
Support heavy fruit clusters if needed. Maintain regular watering throughout fruiting. Harvest ripe keys when fully colored and fragrant. Continue fertilizing for next year's production.

Harvest Tips
Fruit keys mature 6-12 months after flowering and are ready to harvest when fully colored (yellow-orange), fragrant, and slightly soft to pressure. Cut keys with sharp knife at the base. Each tree can produce multiple fruit clusters. Peak season is typically summer through early fall, though fruiting can occur year-round in ideal tropical conditions. Harvest when the individual drupe segments separate easily from the axis.
