🌱 How to Care for Cunjevoi to Prevent Bacterial Leaf Spot?

💧 How to Water

Water thoroughly every 7–10 days, allowing the top 2–3 cm of soil to dry slightly between waterings. Never let the plant sit in waterlogged soil — this is the leading cause of root rot. Reduce watering in winter.

☀️ Lighting

Provide bright, indirect or dappled light. Cunjevoi is an understorey plant that thrives in filtered light beneath a canopy. Avoid direct midday sun, which can scorch the large leaves. Near a north- or east-facing window is ideal indoors.

🪴 Ideal Soil

Use a well-draining mix rich in organic matter. A blend of quality potting mix, perlite, and coco coir works well. Slightly acidic pH of 5.5–6.5 is ideal. Avoid heavy clay soils that retain excess moisture.
