Plant Needs
Sunlight
Requires full sun for optimal berry production; tolerates partial shade in hot climates but may produce fewer cones
Watering
Drought-tolerant once established; water deeply during dry spells and allow soil to dry completely between waterings to avoid root rot
Temperature
Extremely cold-hardy, capable of surviving harsh subarctic winters; tolerates moderate summer heat
Characteristics
- Leaf: Awl-shaped, sharp-pointed, arranged in whorls of three; dark green to blue-green
- Cones: Male cones are small, yellow, release pollen in spring; female cones mature into blue-black berry-like fleshy cones over 2–3 years
- Stem: Woody, densely branching; reddish-brown bark peels in thin strips with age
Care Guide
Watering
Water deeply once weekly during extended dry periods; avoid overwatering
Fertilization
Apply a balanced slow-release fertilizer once in early spring. Avoid over-fertilizing, as excessive nutrients can reduce berry production
Eggshell powder topdressing：Crush dried eggshells into fine powder, sprinkle lightly around the base of the plant in early spring, and work into the top 2 cm of soil to support root healthPruning
- Thin overcrowded branches in late winter to improve airflow and light penetration
- Remove dead, diseased, or damaged branches throughout the growing season
- Shape hedges or topiaries in early spring before new growth emerges; avoid heavy pruning of old wood as it may not regrow
