Judas tree

Fertilizing

Feed your Judas bonsai with a balanced organic fertilizer during the growing season (spring through early fall) using a monthly application schedule. In spring, increase nitrogen levels to promote robust leaf growth and flowering. Switch to a balanced NPK fertilizer (like 10-10-10) during summer months to support overall health and flowering. During dormancy in winter, reduce or stop fertilization entirely to match the tree's natural cycle. For best results, dilute liquid fertilizers to half-strength or use slow-release organic pellets.

The frequency and type of fertilization should be adjusted based on your tree's growth stage and health. Young trees in development may benefit from more frequent feeding, while mature specimens can thrive with less intensive fertilization schedules. Always monitor your tree's response to fertilization and adjust accordingly.

Placement

The Judas bonsai requires 6-8 hours of direct sunlight daily for optimal growth and flowering. Place the tree in a bright location with full sun to partial shade, depending on your climate. During peak summer heat, provide some afternoon shade to prevent leaf scorch. The tree can be grown both indoors and outdoors, but must be protected from frost when temperatures drop below freezing.

For indoor placement, position near a south-facing window where it can receive filtered sunlight. Maintain temperatures between 60-75°F (15-24°C) and protect from drafts. During winter, the tree requires a period of dormancy with cooler temperatures between 40-55°F (4-13°C). Consider using reflective surfaces in shaded areas to maximize light exposure, particularly important for flower production.

Pruning

Structural pruning should be performed during the dormant period in late winter or early spring, just before new growth begins. Start by removing any dead, crossing, or awkwardly positioned branches. When shaping, use sharp pruning shears and make clean cuts just above a node or bud, angling the cut away from the tree to promote healing. Crown reduction can be employed to control size while maintaining the tree's natural form.

Maintenance pruning throughout the growing season helps develop and maintain the desired shape. Regular pinching and defoliation can be used to control growth direction and foliage density. The Judas bonsai responds well to wiring, but take care to wrap wire loosely to avoid damaging the bark. Remove wire before it begins to cut into the branches. After any significant pruning, monitor the tree closely for signs of stress and ensure it receives adequate water and sunlight.

Repotting

Repot your Judas bonsai every 2-3 years in early spring, just before new growth begins. Use a well-draining soil mixture that combines akadama, pumice, and organic matter, maintaining a pH between 6.0 and 7.0. When repotting, carefully prune back the roots, removing any dead or damaged portions while maintaining enough root mass to support the tree.

For older, more established trees, repotting intervals can be extended to 3-4 years. Always use clean tools and a pot with adequate drainage holes. After repotting, place the tree in a sheltered location and keep it protected from strong winds and direct sunlight for several weeks while it recovers. Maintain consistent moisture levels during this period to support root regeneration.

Watering

Maintain consistent soil moisture without waterlogging by checking the top inch of soil daily - water thoroughly when it feels dry to the touch. The Judas bonsai prefers slightly moist conditions but can tolerate brief periods of drought. During summer months, increase watering frequency to compensate for increased evaporation, while reducing frequency during winter dormancy.

Create optimal humidity levels by placing the pot on a humidity tray filled with water and pebbles, particularly important for indoor specimens. Water quality matters - use room temperature water and avoid heavily chlorinated water if possible. Adjust watering based on environmental conditions, pot size, and soil composition, being especially vigilant during the critical spring flowering period.
