Plant Needs
Sunlight
Full sun exposure is required for dense, compact growth; tolerates partial shade but may lose its tight columnar form
Watering
Drought-tolerant once established; water deeply but infrequently to avoid waterlogged soil and root rot
Temperature
Extremely cold-hardy; tolerates hot, dry summers with adequate drainage to prevent heat stress
Characteristics
- Foliage: Scale-like, aromatic dark green leaves, tightly packed along upright stems
- Cones: Female cones are small, blue-black berry-like structures with a waxy coating
- Stem/Bark: Reddish-brown, peeling bark on mature plants; slender, rigid upright branches
Care Guide
Watering
Water newly planted specimens weekly; established plants only need water during extreme drought
Fertilization
Apply slow-release balanced fertilizer once in early spring. Avoid over-fertilization to prevent weak, leggy growth that reduces structural stability
Eggshell powder top-dressing：Crush clean, dried eggshells into fine powder; sprinkle 1–2 tbsp around the base in early spring and work lightly into the topsoil to avoid pest attractionPruning
- Trim stray or overgrown branches in early spring to maintain the narrow columnar form
- Remove dead, diseased, or damaged foliage to improve airflow and reduce pest risk
- Avoid heavy pruning, as dense foliage grows slowly and may not regrow quickly after severe cutting
