How to Grow Stewartia
Stewartia pseudocamellia
Plant in moist, acidic, well-drained soil — Stewartia will not tolerate chalk or waterlogging. Dappled shade suits it best; harsh afternoon sun in summer can scorch the flowers. This slow-growing tree rewards long-term gardeners with white camellia flowers in July-August, blazing autumn colour, and extraordinary mosaic bark year-round. Mulch annually with leafmould and keep the root zone cool and moist. Pruning is almost never needed.

Care Requirements
Light
Dappled shade, avoid afternoon sun
Prefers light woodland shade. Harsh afternoon sun scorches flowers and foliage. Morning sun with afternoon protection is ideal.
Watering
Consistent moisture, never waterlogged
Keep the root zone moist, especially during flowering. Deep watering in dry spells is critical. Dislikes both drought and waterlogging.
Fertilizing
Acidic mulch annually, light ericaceous feed
Mulch with acidic leaf mould in spring. A light ericaceous fertiliser benefits young trees. Avoid high-nitrogen feeds.
Pruning
Minimal, natural form is beautiful
Remove dead or crossing branches in late winter before bud break. The elegant natural shape rarely needs intervention.
