🌱 How to Care for Umbrella Tree to Prevent Scale Insects?

💧 How to Water

Allow the top 30–50% of the potting mix to dry out before watering. In winter or low-light conditions, let it dry even more between waterings. Always ensure water drains freely from the pot to prevent root rot — the most common cause of decline.

☀️ Lighting

Place near a window with bright indirect light for best growth. It adapts to lower light but growth slows and stems become leggy. Variegated cultivars need brighter conditions to maintain their color patterns. Avoid harsh direct afternoon sun which can scorch leaves.

🪴 Ideal Soil

Use well-draining potting mix rich in organic matter. A blend of potting soil with perlite or bark works well. Good drainage is essential — soggy soil quickly leads to root rot. Slightly acidic to neutral pH (6.0–7.5) is ideal.
