Durian young plant care shade windbreak phytophthora root rot stem canker drainage pests humid India trial

The early life of a durian plant in India is the riskiest stage, so the main job is keeping the young plant alive and growing. Give shade for the first couple of years because young leaves scorch in harsh sun, put up a windbreak since the brittle wood and later the heavy fruit are vulnerable to wind, and above all ensure excellent drainage, because durian is very prone to Phytophthora root rot, collar rot and stem canker in wet, poorly drained soil. Plant on raised mounds in heavy rainfall areas, keep the basin mulched but the collar dry, and avoid injuring the trunk. Watch for borers, mealybugs and leaf eating pests, but the disease threat from waterlogging is usually the bigger killer here. Because agronomy is unproven in India, keep close records and learn as you go. For any spray or drench use only labelled products on advice, and confirm a young plant care and disease management plan with a horticulture research station or KVK, since this crop is still experimental in the country.
I lost a couple of young plants to root rot in a wet patch before I shifted the rest onto raised mounds with good drainage. Shade and a windbreak for the first years saved the others. Treat each plant like a baby.
Keeping the collar dry is the lesson I learned the hard way. Mulch the basin but do not pile it against the stem. In our humid climate the fungal rots are the real enemy of young durian.
