Fertilizing
Apply liquid fertilizer weekly during the spring through autumn growing seasons, ensuring the soil is moist before application to prevent root burn. During winter, reduce fertilizing to once monthly. For additional nutrition during summer months, you can supplement with solid organic fertilizer pellets. When growing indoors, use a lighter hand with nitrogen-rich fertilizers, as too much can lead to excessive growth and larger leaves that are less desirable for bonsai aesthetics.
Placement
The Schefflera bonsai thrives as an indoor tree, making it perfect for year-round indoor cultivation. While it can tolerate low light conditions, providing bright indirect sunlight will promote better growth and smaller, more compact leaves. Maintain temperatures between 18-22°C (65-72°F) and never let it drop below 10°C (50°F). This tropical species appreciates higher humidity, which can be achieved using a humidity tray or regular misting. Keep the tree away from cold drafts, especially during winter months when windows are opened for ventilation.
Pruning
Focus on thoughtful structural pruning during spring and early summer when the tree can heal quickly from cuts. When pruning, remember that new shoots will grow in the direction of the leaf directly below the cut point. For established, healthy trees, you can defoliate and trim branch tips simultaneously to encourage ramification and smaller leaf development. The Schefflera's soft wood makes it prone to snapping during wiring, so use extreme caution when bending branches. Consider focusing more on pruning techniques rather than wiring to achieve your desired shape, as the species responds well to pruning-based training methods.
Repotting
Perform repotting every two years during spring using a standard bonsai soil mix. Exercise special care when handling the fleshy roots as they break easily during the repotting process. If the tree shows signs of stress or weakness, it's better to delay repotting until it regains strength. The repotting process provides an opportunity to inspect and manage the root system, removing circling or tangled roots while maintaining enough root mass to support healthy growth.
Watering
Maintain consistent soil moisture without allowing the soil to become waterlogged. While the tree likes moist conditions, proper drainage is essential to prevent root rot. During winter months, reduce watering frequency but pay special attention if the tree is placed near heating sources, as this can quickly dry out the root ball. Using a fine-nozzle watering can helps simulate natural rainfall and ensures even water distribution without disturbing the soil structure.
