🌱 How to Care for Swiss Cheese Vine to Prevent Scale Insects?

💧 How to Water

Water every 7 days, or when the top 1–2 cm of soil is dry. Never let the soil dry out completely — M. obliqua is highly sensitive to underwatering. Avoid waterlogging, which quickly leads to root rot.

☀️ Lighting

Place in bright indirect light, 1,000–10,000 lux. An east or north-facing window is ideal. Avoid direct sunlight, which scorches its delicate, mostly-hole leaves. Low light will stunt growth and reduce fenestration.

🪴 Ideal Soil

Use a very well-draining, airy mix: orchid bark, perlite, and peat or coco coir. The roots need excellent aeration. Standard potting soil is too dense and risks root rot.
