- Light: Pemphis acidula bonsai thrive in full sunlight. Place your bonsai in a location where it can receive at least 6-8 hours of direct sunlight each day. If grown indoors, provide bright, indirect light or use grow lights to supplement.
- Watering: These bonsai prefer slightly moist soil. Water thoroughly when the top inch of soil feels dry to the touch, but avoid waterlogging the soil. Allow excess water to drain away freely to prevent root rot. Adjust watering frequency based on environmental conditions and the season.
- Soil: Use a well-draining bonsai soil mix that allows for good aeration and drainage. A mix of akadama, pumice, and lava rock is commonly used for Pemphis acidula bonsai. Repotting is typically done every 1-2 years to refresh the soil and prevent root binding.
- Fertilizing: Feed your Pemphis acidula bonsai with a balanced, water-soluble fertilizer during the growing season (spring and summer). Dilute the fertilizer to half strength and apply every two weeks. Reduce or stop fertilizing during the dormant season (fall and winter).
- Pruning and Training: Regular pruning helps maintain the bonsai’s shape and encourages ramification (branching). Use sharp bonsai shears to remove unwanted growth, including long shoots and branches that disrupt the desired silhouette. Wiring can be used to guide the branches into the desired position, but care must be taken to avoid damaging the tree’s delicate bark.
- Pests and Diseases: Keep an eye out for common bonsai pests such as aphids, spider mites, and scale insects. Inspect your bonsai regularly and treat any infestations promptly with insecticidal soap or horticultural oil. Avoid overwatering to prevent fungal diseases such as root rot.
