Brazilian Rain Tree Bonsai problems — and how to fix them
Brazilian Rain Tree Bonsai (Chloroleucon tortum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaflet drop from cold or dryness
Temperatures below about 13°C or letting the rootball dry out triggers leaf shedding. Keep it warm and evenly moist year-round.
Spider mites and scale
Dry indoor air encourages mites; scale can hide on stems. Raise humidity, inspect regularly, and treat with insecticidal soap or horticultural oil.
Thorn injuries during styling
The long, sharp spines make wiring and pruning hazardous. Wear gloves and work carefully around the branch structure.
Slow recovery after hard work
It resents heavy root or canopy reduction when not actively growing. Do major work in warm weather when it can flush back vigorously.
