🌱 How to Care for Yucca to Prevent Mealybugs?

💧 How to Water

Water only when the top 5 cm of soil is completely dry, typically every 10–14 days in summer. In winter, reduce to once a month or less. Never let water sit in the crown or pot saucer — root rot is the main killer of yuccas.

☀️ Lighting

Yucca needs bright, direct or indirect light. Indoors, place near a south or west-facing window. It tolerates full outdoor sun well. Avoid deep shade — insufficient light causes etiolation and weakens the plant significantly.

🪴 Ideal Soil

Use a sandy, gritty, well-draining mix — a 1:1 blend of regular potting soil and coarse sand or perlite works well. Never use heavy, moisture-retaining soils. Slightly acidic to neutral pH (6.0–7.5) is ideal.
