Fertilizing
During the flowering season, avoid fertilizing your poinsettia bonsai entirely. Once the flowering period ends, begin fertilizing in mid-spring when new growth emerges. Use a balanced houseplant fertilizer formulated for succulents and cacti, applying it every two to three weeks. Look for fertilizers with higher nitrogen content to encourage leafy growth rather than excessive blooming. During the growth phase, switch to fertilizers rich in potassium, then transition to phosphorus-rich ones before the flowering period to enhance bract coloration and blooming.
Placement
Position your poinsettia bonsai in bright but indirect sunlight where it can receive 6-8 hours of filtered light daily. Keep the plant in temperatures between 65-75°F (18-24°C) during the day, with slightly cooler nighttime temperatures between 45-55°F (7-13°C). Protect from cold drafts and avoid placing directly on cold windowsills as this can damage the foliage. During summer months, the plant can be moved outdoors but must be brought inside before temperatures drop too low. Maintain good air circulation around the plant while avoiding direct exposure to air conditioning or heating vents.
Pruning
Major pruning should be performed after flowering has finished, typically in early spring. Remove all foliage except for 2-3 small leaves near the top of each stem. Throughout the growing season, regularly pinch back new growth tips to encourage bushiness and maintain the desired shape. Dead, diseased, or crossing branches should be removed immediately using sharp, clean pruning shears. Avoid traditional wiring techniques as poinsettia stems are quite brittle. Instead, focus on directional pruning to achieve the desired form. Remember to wear gloves when pruning as the milky sap can cause skin irritation.
Repotting
Repot your poinsettia bonsai every 2-3 years in early spring after flowering has finished. Use a well-draining bonsai soil mix consisting of equal parts akadama, pumice, and peat moss. Choose a glazed ceramic container with adequate drainage holes that is slightly larger than the root ball. When repotting, gently trim back approximately one-third of the roots while being careful not to damage the central root system. Ensure the new pot has proper drainage and avoid planting too deeply as this can lead to root rot.
Watering
Water thoroughly when the top 1-2 inches of soil feels dry to the touch. During watering, saturate the soil completely until water runs freely from the drainage holes, but never allow the plant to sit in standing water. Reduce watering frequency during winter months when growth naturally slows. Maintain consistent soil moisture - neither waterlogged nor completely dry. Consider using a humidity tray or regular misting to increase ambient moisture, especially during flowering periods. Always check soil moisture with your finger before watering to avoid overwatering issues.
