Plant Needs
Sunlight
Full sun exposure is optimal for dense, silvery foliage; tolerates partial shade in extreme summer heat to prevent leaf scorch
Watering
Water deeply when the top 5–10 cm of soil is dry; drought-tolerant once established, avoid overwatering to prevent root rot
Temperature
Tolerates light frost down to -5°C; avoid prolonged exposure to temperatures below -5°C; thrives in warm, dry climates
Characteristics
- Leaf: Juvenile leaves are round, silvery-blue, sessile; adult leaves are lanceolate, gray-green, aromatic when crushed
- Flower: Creamy-white, fluffy umbellate inflorescences
- Stem/Bark: Smooth, shedding bark in patches, ranging from gray to brown
Care Guide
Watering
Water deeply every 7–10 days; reduce frequency during periods of heavy rainfall
Fertilization
Apply balanced slow-release fertilizer once at the start of growth. Avoid over-fertilizing, as excessive nutrients can reduce leaf silvering
Banana peel compost tea：Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water for root drenching; discard solid peels to prevent pest infestationsPruning
- Prune in late winter to shape the tree and remove dead, damaged branches
- Trim juvenile foliage to maintain a compact, bushy form for potted specimens
- Remove suckers from the base to promote growth of the main trunk
- Avoid heavy pruning in summer to prevent sunscald on exposed bark
