🌱 How to Care for Kahikatea to Prevent Aphids?

πŸ’§ 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.

β˜€οΈ 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.

πŸͺ΄ 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.
