Common Pests & Diseases
Transplant
4-6 feet
Perfect timing to move evergreen laburnum is during mid to late spring, capitalizing on the temperate conditions ideal for root establishment. Ensure a sunny location with well-draining soil for optimal growth. Gentle handling is key to avoid root disturbance.
Transplant Techniques 
Temperature
0 - 41 ℃
Evergreen laburnum is originally from a native environment with temperate climates. Its optimal growth temperature ranges between 68 to 95 °F (20 to 35 ℃). Thriving best within this range, steps to adjust to seasonal temperature changes may be essential due to its sensitivity.
Temp for Healthy Growth 
Pruning
Early spring, Winter
This evergreen shrub, noted for its bright yellow flowers, benefits from selective pruning to maintain shape and promote vigorous growth. Prune evergreen laburnum in early spring before new growth begins, or in winter during dormancy. Remove dead or damaged branches, thin out overcrowded areas, and trim back leggy stems to encourage bushier growth. Pruning not only enhances the plant's appearance but also improves its overall health and flower production.
