How to Grow Golden Rain Tree
Koelreuteria paniculata
Golden rain tree is a sun-loving, drought-tolerant specimen tree grown for its summer yellow flower panicles, papery seed pods, and pinnate foliage with a bronze flush when young. It thrives in hot, dry, exposed positions where many other trees struggle — ideal for urban gardens and hot dry slopes. Plant in full sun and well-drained soil. Pruning needs are minimal; remove dead or crossing branches in late winter. Established trees are very self-sufficient.
Yearly Lifecycle
Care Essentials
Apply a balanced slow-release fertiliser in spring when young. Established trees need little feeding. Avoid high-nitrogen feeds that promote soft growth at the expense of flowering.
Watch For

- Canker
- Leaf spot

Gleditsia, Cercis, Catalpa, Ornamental grasses
Care Requirements
Light
Full sun, hot position
Thrives in full sun and hot, dry conditions. Plant in the warmest spot available. Tolerates reflected heat from walls and paving where other trees struggle.
Watering
Drought-tolerant once established
Water during dry spells in the first 2-3 years. Once established, very drought-tolerant and thrives in hot dry conditions with minimal supplemental watering.
Fertilizing
Slow-release when young, none when mature
Apply a balanced slow-release fertiliser in spring when young. Established trees need little feeding. Avoid high-nitrogen feeds that promote soft growth over flowering.
Pruning
Minimal, late winter only
Prune in late winter while fully dormant. Remove dead, damaged, or crossing branches only. The tree naturally develops an attractive rounded crown with minimal intervention.
