🌱 How to Care for Spotted Laurel to Prevent Anthracnose?

💧 How to Water

Water every 7–14 days, allowing the top 2–3 cm of soil to dry between sessions. Reduce watering in winter. Avoid waterlogged soil, which rapidly causes root rot. Established outdoor plants have good drought tolerance.

☀️ Lighting

Spotted Laurel excels in partial to full shade. Avoid direct midday sun, which causes leaf scorch — especially on variegated varieties. It can tolerate morning sun. Indoors, a bright spot away from direct rays is ideal.

🪴 Ideal Soil

Use a fertile, moisture-retentive but well-drained loamy soil. Amend with organic matter if your soil is sandy or compacted. Tolerates a wide pH range (5.5–7.0). Avoid waterlogged or clay-heavy soils without drainage.
