🌱 How to Care for Frangipani to Prevent Anthracnose?

💧 How to Water

Water every 7-10 days during spring and summer, only when the soil is completely dry. During fall and winter dormancy, reduce watering to every 3-4 weeks or stop entirely if the plant drops all its leaves. Overwatering causes root rot rapidly in this species — err on the dry side.

☀️ Lighting

Requires at least 6 hours of direct sunlight per day to flower properly. The more sun, the more blooms. Some afternoon shade is tolerated in extreme heat, but avoid shaded or low-light positions — these will prevent flowering.

🪴 Ideal Soil

Use a well-draining, lightweight mix — a combination of potting soil, coarse sand, and perlite is ideal. Avoid heavy clay soils that retain moisture. Ideal pH is between 6.0 and 7.0.
