Troubleshooting
Rukam problems — and how to fix them
Rukam (Flacourtia rukam) 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.
Fruit astringency
Freshly picked fruit is very astringent; leave on the tree until fully ripe or place in a bag to blette (soften) after picking.
Scale insects
Treat with horticultural oil spray at early infestation to prevent population build-up.
Fungal leaf blight
Common in wet tropical conditions with poor airflow; prune for ventilation and apply copper fungicide.
Thorns and pruning difficulty
Heavy gloves and long-handled tools are essential; plan the tree's location to minimise conflict.
Root rot
Avoid planting in depressions where water collects; raised beds are effective in high-rainfall areas.
