🌱 How to Care for Ti Plant to Prevent Anthracnose?

💧 How to Water

Water approximately every 7 days, allowing the top 2-3 inches of soil to dry slightly between waterings. Reduce frequency in fall and winter. Use room-temperature, preferably fluoride-free water, as fluoride can cause brown leaf tips.

☀️ Lighting

Place in bright, indirect light — near a filtered window or in a spot with several hours of diffused light per day. Avoid harsh direct sun, which scorches the leaves. Colorful-leaved varieties need more light to maintain vibrant colors.

🪴 Ideal Soil

Use a rich, well-draining potting mix — a blend of quality potting soil and perlite (2:1 ratio) works well. Target a soil pH of 5.5–6.5. Avoid heavy clay-based soils that stay waterlogged.
