🌱 How to Care for Kousa Dogwood to Prevent Underwatering?

💧 How to Water

Water deeply about once a week for the first two years and during dry spells. Established trees cope better, but drought and reflected heat scorch the leaf edges. Mulch over the roots helps keep the soil moist.

☀️ Lighting

Full sun to part shade. It flowers best in sun; where summers are very hot, give it afternoon shade and keep it away from walls and paving that reflect heat.

🪴 Ideal Soil

Rich, moist, well-drained loam, ideally acidic to neutral. It tolerates clay but not shallow chalky soils.
