🌱 How to Care for Dappled Willow 'Hakuro Nishiki' to Prevent Web-spinning sawflies?
💧 How to Water
Keep the soil consistently moist—this willow does not tolerate drought, which can cause leaf scorch and curling. During hot, dry summer periods, water generously; container plants may require daily watering. It also tolerates occasionally waterlogged sites well.
☀️ Lighting
It grows best in full sun, which intensifies the pink and white variegation of the leaves; it also tolerates light partial shade, though the coloring will be less vivid. In very hot regions, some light afternoon shade is beneficial.
🪴 Ideal Soil
Prefers fertile, humus-rich, and well-drained soil with a slightly acidic to neutral pH (5.5-7.5) that remains consistently moist. It handles clay and heavy soils well, provided there is adequate drainage.
