Fertilizing
Feed your Weigela bonsai every two weeks throughout the growing season with a balanced bonsai fertilizer. During the dormant winter months, reduce or stop fertilization entirely to match the tree's natural growth cycle. Using organic fertilizer pellets or liquid fertilizer provides essential nutrients that help maintain the tree's health and promote the vibrant flowering display that Weigela is known for.
Placement
Weigela bonsai requires a location with full sun but appreciates some shade during the peak intensity of summer afternoons. This adaptable species is hardy down to -10°C, making it suitable for outdoor cultivation year-round. Protect it from excessive heat and intense afternoon sun which can cause leaf burn. When choosing a display location, ensure the tree receives at least 6 hours of direct sunlight daily while providing some protection during the hottest parts of the day.
Pruning
Regular pruning is essential for maintaining the Weigela bonsai's shape and encouraging proper growth patterns. Prune during the dormant season in late winter or early spring when the buds begin to extend. Weigela bonsai are particularly well-suited for cascade and informal upright styles in medium to large sizes. When wiring, use wire with thickness matching the branch diameter - too thick will damage the bark, while too thin won't be effective in training the branches. Structural pruning should focus on removing dead, damaged, or crossing branches to improve the tree's overall health and appearance.
Repotting
Repot your Weigela bonsai every two to three years in early spring as the buds begin to extend. Choose a well-draining soil mix with a neutral to slightly acidic pH between 5-6, but not exceeding 7. When repotting, avoid aggressive root pruning and don't remove too much of the root mass at once. The tree will require a suitable new pot and appropriate soil mix for optimal growth. Professional repotting services or expert advice can be valuable for maintaining proper root health during this crucial maintenance task.
Watering
Water your Weigela bonsai based on careful observation rather than a fixed schedule. Allow the top centimeter of soil to dry between waterings to ensure proper aeration of the roots. The soil should retain moisture while remaining well-draining to prevent waterlogging which can lead to root problems. During dry periods or after repotting, maintain appropriate humidity levels by misting the foliage regularly. Monitor soil moisture levels consistently and adjust watering frequency based on weather conditions and the tree's specific needs.
