Troubleshooting
Red Durian problems — and how to fix them
Red Durian (Durio dulcis) 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 drop before maturity
Water stress, nutrient deficiency, or pollination failure causes premature drop. Maintain consistent irrigation and potassium supply.
Patch canker (Phytophthora)
Water-soaked bark lesions that ooze gum. Improve drainage and treat with phosphonate-based fungicides.
Fruit borer
Caterpillar larvae tunnel into developing fruit. Remove affected fruit promptly and use pheromone traps.
Slow establishment
Young trees are sensitive to transplant shock. Water daily for the first six months and provide temporary shade during the hottest part of the day.
Wind damage
Large flat-sided fruits on long stalks are vulnerable to storm winds. Provide windbreaks and harvest when near-ripe.
