1. Positioning and Light:
- Sunlight: Junipers require several hours of direct sunlight daily. If kept indoors, ensure they are placed near a south-facing window or under grow lights.
- Outdoor Living: Junipers are best suited for outdoor living. They require a dormant period in winter with colder temperatures. However, protect them from extreme cold or frost.
2. Watering:
- Frequency: Junipers prefer their soil to be slightly moist but not soggy. Water when the top layer of soil feels dry. Overwatering can lead to root rot.
- Method: Water thoroughly until excess moisture drains from the bottom. Ensure the pot has adequate drainage holes.
3. Humidity:
- While Junipers are tolerant of various humidity levels, they appreciate occasional misting, especially during hotter months.
4. Soil and Fertilizing:
- Soil: A well-draining soil mix is crucial. Consider a mix of akadama, lava rock, and pumice in equal parts.
- Fertilizing: Feed your Juniper with a balanced bonsai fertilizer every two weeks during the growing season (spring to early autumn). Reduce feeding frequency in winter.
5. Pruning and Shaping:
- Pruning: Regularly prune to maintain the desired shape. Focus on removing dead or excessive growth.
- Wiring: Junipers respond well to wiring, allowing for intricate designs. Apply wire during the growing season but monitor to prevent the wire from cutting into the bark.
6. Repotting:
- Repot Junipers every 2-4 years for younger trees and every 4-6 years for mature ones. Spring is the ideal time for repotting.
- Trim up to a third of the root mass during repotting to encourage healthy growth.
7. Pests and Diseases:
- Junipers can be susceptible to spider mites, aphids, and fungal diseases. Regularly inspect and treat promptly if issues arise.
- Neem oil or insecticidal soap can be effective treatments.
8. Common Issues:
- Brown Foliage: This can be a sign of spider mite infestation or root rot due to overwatering.
- Weak Growth: Often a result of insufficient light or inadequate fertilization.
