🌱 How to Care for Katsura tree to Prevent Leaf Tip Necrosis?

💧 How to Water

Keep the soil evenly moist, especially during the first 2-3 years and during dry summers—the Katsura tree is shallow-rooted and tolerates drying out poorly, which can lead to leaf scorch. Avoid overhead watering in humid weather to reduce the risk of powdery mildew.

☀️ Lighting

Thrives best in full sun to partial shade. Full sun provides the most vibrant autumn colors, but protect the tree from harsh afternoon sun and drying winds, which can scorch the leaves.

🪴 Ideal Soil

Prefers nutrient-rich, moist but well-drained soil with a pH ranging from slightly acidic to neutral (approx. 5-7). Leaf color is often more intense in acidic soil, while lime-rich soil can result in pale foliage.
