Sunlight
Requires at least 6 hours of direct sunlight daily to maintain vibrant silvery-blue foliage; tolerates partial sun but may dull color
Watering
Water deeply when the top 5–7 cm of soil is completely dry; avoid overwatering to prevent root rot
Temperature
Hardy to -20°C; tolerates hot, dry conditions but benefits from light shade during extreme summer heat in arid regions
Characteristics

- Cones: Female cones are small, berry-like, blue-black when mature; male cones are tiny, yellow-brown
- Stem: Woody, branching densely from the base to maintain a tight, mounded form
Care Guide
Watering
Water deeply every 7–10 days during prolonged dry spells
Fertilization
Apply a slow-release granular evergreen fertilizer once in early spring. Avoid high-nitrogen fertilizers, which may cause excessive green growth and dull blue foliage
Eggshell powder topdress：Crush dried eggshells into a fine powder; sprinkle 1–2 tablespoons around the base of the shrub; water lightly to help nutrients absorb into the soilPruning
- Remove dead, damaged, or diseased branches in early spring to maintain air circulation
- Trim stray branches in late spring to preserve the compact star-like shape
- Avoid heavy pruning, as junipers have limited regrowth from old wood
