π± How to Care for Kahikatea to Prevent Phytophthora Root Rot?
π§ How to Water
Keep the root zone constantly moist β kahikatea is a swamp-forest species and does not tolerate drying out. Never let it experience prolonged drought; supplement rainfall with irrigation in dry spells, especially for young trees.
βοΈ Lighting
Grow in full sun for best form once established, though young trees tolerate part shade or shelter beneath a forest canopy. Deep shade over many years will produce a leggier, less vigorous tree.
πͺ΄ Ideal Soil
Best in rich, poorly-drained to swampy soils (peaty or silty loams); it thrives where many other trees would suffer from wet feet. Avoid dry, sandy, or fast-draining sites.
