Troubleshooting
Pulasan problems — and how to fix them
Pulasan (Nephelium mutabile) 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.
Strictly tropical requirement
Pulasan tolerates cold even less than rambutan and fails in subtropical or seasonally dry climates; it needs a genuinely equatorial, humid environment.
Slow to bear from seed
Seedlings can take five to six years or more to fruit and are variable; grafted trees crop sooner and truer to the parent.
Flower and fruit drop
Drought, low humidity or irregular watering during flowering causes drop; maintain steady moisture and high humidity throughout cropping.
Fruit flies and rind pests
The sweet fruit attracts fruit flies and chewing insects; bagging clusters and prompt removal of fallen fruit help protect the crop.
Prevent pulasan problems before they start
Most pulasan issues are care-mismatch, not bad luck. Dial in the basics:
