Plant Needs
Sunlight
Bright direct to partial sun; tolerates partial shade, but fronds may become leggy with insufficient light
Watering
Water thoroughly when the top 5–7 cm of soil is dry; avoid overwatering to prevent root rot
Temperature
Thrives at 18–25℃; protect from frost below 10℃ and extreme heat above 35℃
Characteristics
- Leaf: Dark green, glossy pinnate fronds; stiff, arching, up to 1 m long
- Stem: Thick, cylindrical trunk-like caudex; covered in persistent leaf bases
- Reproductive Structures: Male cones are tall, cylindrical; female cones are large, rounded with orange seeds
Care Guide
Watering
Keep soil evenly moist but not waterlogged; allow the top 2–3 cm to dry between waterings
Fertilization
Diluted balanced slow-release fertilizer once monthly. Avoid high-nitrogen fertilizers, which can damage the cycad's root system
Eggshell powder topdress：Crush dried eggshells to a fine powder; sprinkle 1–2 tbsp on the soil surface and gently work into the top layer to avoid disturbing rootsPruning
- Remove brown, dead fronds at the base to maintain appearance and improve airflow
- Trim yellowing fronds to prevent pest infestations and reduce nutrient waste
- Avoid cutting healthy fronds, as cycads grow slowly and fronds take several months to mature
Toxicity
Warning: this plant may be toxic.
Pets & Humans
Pets: ASPCA: Highly toxic; cycasin causes liver failure, potentially fatal if untreated
Humans: Seeds contain cycasin, which causes liver damage if ingested; processed seeds may be safe but raw consumption is toxic
Garden Uses & Culture
Culture: Symbolizes longevity and resilience in traditional Japanese garden design
Usage: Ornamental foliage; historically used for processed starch from seeds (after toxin removal)
