🌱 How to Care for Chinese Juniper to Prevent Spider Mites?

💧 How to Water

Water when the top of the soil feels slightly dry. For bonsai, check moisture daily in summer — the tree may need watering every day in hot weather. Never allow the roots to sit in waterlogged soil, as root rot is the most serious threat to this species.

☀️ Lighting

Place in full sun with at least 6 hours of direct sunlight daily. Chinese Junipers do not tolerate shade well — insufficient light leads to weak, leggy growth and increased susceptibility to pests and diseases. This is strictly an outdoor species.

🪴 Ideal Soil

Use a well-draining soil mix. For bonsai, a blend of akadama, pumice, and coarse sand is ideal. In garden settings, the plant tolerates sandy, rocky, clay, and loam soils as long as drainage is adequate. Avoid waterlogged or compacted soils.
