The water requirements of Himalaya pine are moderate. They rely on snowmelt and seasonal rains in their natural habitats. Since excessive water or wet conditions can cause root rot and other fungal infections, these trees prefer well-drained soils. Additional watering during the early growth stages or during extended dry periods can aid in the establishment of a robust root system in lower-altitude or drier locales. Although these trees can withstand some drought once they reach maturity, they can benefit from sporadic irrigation during protracted dry spells.
