🌱 How to Care for Cabbage Tree to Prevent Fusarium Wilt?

💧 How to Water

Water young plants regularly during the first growing season. Once established, Cabbage Tree is highly drought-tolerant — water only every 10 days or when the soil is dry. Reduce watering in autumn and winter. Avoid waterlogged soil to prevent root rot.

☀️ Lighting

Thrives in full sun. Green-leaved varieties can handle direct sunlight; coloured cultivars prefer bright indirect light. Position in a south- or west-facing spot for best growth and leaf colour intensity.

🪴 Ideal Soil

Plant in well-draining soil amended with grit or sand if needed. Tolerates sandy, loamy, and chalky soils. Neutral to slightly acidic or alkaline pH (6.0–7.5) is ideal. Heavy clay must be improved with drainage material.
