Characteristics
- Leaf: Pinnately compound, 10–25 cm long; oval, bright green leaflets with smooth margins, turning yellow in fall
- Flower: Dense drooping racemes of fragrant white pea-like flowers, 10–20 cm long
- Stem/Bark: Young stems have paired sharp spines at leaf nodes; mature bark is dark brown and deeply furrowed
Care Guide
Water young trees weekly during dry spells; established trees need only occasional deep watering during extended droughts
Apply a balanced slow-release fertilizer once in early spring for young trees. Mature trees do not require regular fertilization as they fix nitrogen via root nodules
Composted banana peel tea：Compost banana peels for 2–3 weeks to break down organic matter; steep in water for 24 hours, dilute 1:20 for root drench; avoid raw peels to prevent pest infestations- Remove dead, damaged, or crossing branches in late winter to early spring before new growth emerges
- Thin crowded branches to improve airflow and light penetration throughout the canopy
- Trim suckers regularly to maintain tree form and prevent overcrowding of surrounding areas
- Avoid heavy pruning as it can stimulate excessive sucker growth and reduce flowering
