🌱 How to Care for Kamchatka Bugbane to Prevent Leaf Spot?

💧 How to Water

Keep soil evenly moist at all times; the foliage scorches quickly if it dries out. Water deeply about once a week during dry spells, more often in containers or sandy soil, and mulch generously to conserve moisture.

☀️ Lighting

Best in partial or dappled shade. Full shade causes leggy growth, greener (less colorful) foliage on dark-leaved cultivars, and fewer flowers; full sun scorches leaves unless soil stays constantly moist and the climate is cool.

🪴 Ideal Soil

Plant in rich, deep, humus-laden soil that drains well but never fully dries out. Work in generous compost or leaf mold at planting time and reapply as a yearly mulch to maintain organic content and moisture retention.
