Plant Needs
Sunlight
Full sun exposure is preferred; tolerates partial shade in extreme summer heat to prevent leaf scorch
Watering
Highly drought-tolerant; water deeply only during prolonged dry periods, as overwatering can cause root rot
Temperature
Hardy to light frost (-5°C) and withstands high summer temperatures up to 40°C in arid regions
Characteristics
- Leaf: Long, narrow, grass-like leaves form a dense, silvery-green rosette atop the thickened trunk
- Flower: Tall, cylindrical flower spike (up to 3 m) bearing small, creamy-white, fragrant blooms
- Stem/Bark: Thick, blackened trunk covered in layers of accumulated dead leaf bases
Care Guide
Watering
Water deeply once every 2–3 weeks if natural rainfall is insufficient
Fertilization
Diluted low-nitrogen liquid feed once every 2 months. Use a low-nitrogen formula to support slow, steady growth without promoting excessive foliage
Eggshell powder topdressing：Crush dried, clean eggshells into a fine powder; sprinkle a thin layer on the soil surface around the base of the tree, avoiding direct contact with the trunk to prevent rotPruning
- Remove dead, brown outer leaves from the rosette to maintain a tidy appearance and improve airflow
- Trim spent flower spikes at the base after blooming to conserve the plant’s energy reserves
- Avoid cutting into the thick, woody trunk, as it has limited regenerative capacity
