🌱 How to Care for Lizard Vine to Prevent Leaf Spot?

💧 How to Water

Water thoroughly every 5–7 days during the summer, allowing the top layer of soil to dry out between waterings. Reduce watering to approximately every two weeks in the winter. Avoid standing water in the pot—root rot is the most common cause of issues. Use room-temperature water and always ensure the pot has adequate drainage holes.

☀️ Lighting

Tetrastigma obtectum thrives best in low to partial indirect light, ideally placed near an east- or north-facing window, or one to two meters away from a larger window. It has a low tolerance for direct sunlight, which can scorch the leaves. Low-to-medium light conditions are optimal—the plant is well-suited for darker rooms and terrarium setups.

🪴 Ideal Soil

Use a nutrient-rich, well-draining soil mix—ideally one part potting mix, one part perlite, and one part vermiculite. A pH between 6.0 and 7.5 is optimal. Ensure there are sufficient drainage holes in the pot. Repot and refresh the soil every two years in the spring, as the plant grows quickly and can become root-bound.
