Quercus palustris (Pin Oak, Swamp Oak)

How to grow Quercus palustris (Swamp Oak) in NZ

Quercus palustris, or Swamp Oak, grows well in NZ in full sun and moist, well-drained, slightly acidic soil. It tolerates occasional wet conditions, making it suitable for low-lying or damp sites. Water regularly during the first few years to establish deep roots, then only in extended dry periods. Apply a slow-release fertiliser in spring and mulch around the base to conserve moisture. Prune in late winter to remove damaged or crossing branches and to maintain a strong framework.

Quercus palustris (Swamp Oak) care tips

Water young Quercus palustris trees regularly during dry periods to encourage strong root growth, then reduce watering once established. Mulch around the base to retain soil moisture and suppress weeds, keeping mulch away from the trunk. Feed in spring with a slow-release fertiliser to promote healthy growth and vibrant foliage. Prune in late winter or early spring to remove dead, damaged, or crossing branches, and protect young trees from strong winds until well established.

Tree size, spacing, and growth rate

Quercus palustris typically grows 15–25 m tall and 10–15 m wide with a moderate growth rate. Space trees at least 8–10 m apart to allow for their upright, pyramidal form and healthy airflow.
