🌱 How to Care for Candle Plant to Prevent Whiteflies?

💧 How to Water

Water when the top 1–2 inches of soil feel dry, typically every 7 days. Always water thoroughly until excess drains from the pot base, then discard the drained water to prevent root rot. Avoid letting the plant sit in standing water.

☀️ Lighting

Prefers bright indirect light or dappled sun. Tolerates a few hours of gentle morning sun but avoid prolonged exposure to intense midday sun, which can scorch the colourful leaves. Indoors, a bright east- or west-facing windowsill works well.

🪴 Ideal Soil

Use a well-draining mix of potting soil, perlite, and peat moss at roughly equal ratios. Target pH 6.0–7.0. Good drainage is critical — soggy soil rapidly leads to pythium or phytophthora root rot.
