Knightia excelsa Care Tips

Plant Knightia excelsa in full sun to partial shade with well-drained, fertile soil. Water regularly during the first 1–2 years to ensure strong establishment, especially in dry periods. Mulching helps to retain moisture and suppress weeds. It tolerates light frost and wind once established. Prune lightly in early spring to shape if needed.

Plant Size and Spacing

Knightia excelsa typically grows 8–15 metres tall and 3–5 metres wide, forming a narrow, upright tree. When planting, space trees 3–5 metres apart to allow for natural spread and canopy development. This spacing is ideal for shelterbelts, native groves, or as specimen trees in larger gardens. For dense screening, a closer spacing of 2.5–3 metres may be used.
