Troubleshooting
Durian problems — and how to fix them
Durian (Durio zibethinus) 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.
Phytophthora root and stem rot
Durian is highly susceptible to Phytophthora, especially in poorly drained soil; plant on mounds, ensure sharp drainage and avoid overwatering or trunk wounds.
Very long time to fruit
Seedlings may take eight to fifteen years to bear; use grafted trees for fruit in four to six years and to fix a known cultivar.
Falling-fruit and spine hazard
Heavy, spiny fruit drop unpredictably and can injure people or pets below; harvest carefully and keep the drip zone clear when fruit is mature.
Strict climate requirement
Durian fails outside hot, humid, frost-free lowlands; cool spells, drought or low humidity stunt growth and prevent cropping.
Prevent durian problems before they start
Most durian issues are care-mismatch, not bad luck. Dial in the basics:
