Cornus controversa (Giant Dogwood)

How to grow Cornus controversa in NZ

Cornus controversa, often called the Giant Dogwood, grows well in New Zealand when planted in a sunny or lightly shaded, sheltered spot with free‑draining, fertile soil. Plant in spring or autumn and water regularly while establishing to encourage strong root growth. Mulch around the base to retain moisture and suppress weeds, keeping it clear of the trunk. Prune lightly in winter to remove damaged or crossing branches and maintain its elegant, tiered shape. Protect young trees from strong winds and heavy frost.

Cornus controversa care tips

Cornus controversa is relatively low-maintenance in New Zealand with the proper care. Plant it in fertile, free‑draining soil in full sun or light shade, and water regularly during the first two years to establish strong roots. Mulch around the base to conserve moisture and reduce weeds, keeping mulch away from the trunk. Prune lightly in winter to remove damaged or crowded branches and maintain its natural tiered form. Protect young trees from harsh winds and heavy frosts for the best results.

Plant Size and Spacing

Cornus controversa typically grows 6–10 m tall and 4–6 m wide, forming an elegant, tiered canopy that makes it a striking feature tree.
