🌱 How to Care for Arrowhead Vines to Prevent Bacterial Leaf Spot?

💧 How to Water

Water when the top inch of soil feels dry — approximately every 7 days in summer, every 10-14 days in winter. Avoid waterlogging; overwatering is the leading cause of root rot. Never let the pot sit in standing water.

☀️ Lighting

Prefers bright to medium indirect light. Tolerates lower light but variegated cultivars may revert to green under insufficient light. Avoid direct sunlight, which scorches the leaves. An east- or west-facing window is ideal.

🪴 Ideal Soil

Use a well-draining aroid mix: equal parts potting soil, perlite, and orchid bark. Target pH between 5.5 and 6.5. Avoid dense, moisture-retaining soils that promote root rot.
