🌱 How to Care for Caribbean Agave to Prevent Anthracnose?

💧 How to Water

As a desert succulent, Caribbean Agave needs very infrequent watering. Allow the soil to dry out completely between waterings — roughly every 3 weeks in summer, once a month in winter. Never allow water to pool at the base or sit in saucers. Overwatering causes root rot, the leading cause of death.

☀️ Lighting

Requires full sun for best growth — at least 6 hours of direct sunlight daily. Tolerates partial shade but will grow more slowly and less vigorously. Indoors, place as close as possible to a south- or west-facing window for maximum light.

🪴 Ideal Soil

Prefers sandy or well-draining soil with pH between 6.0 and 7.5. Mix coarse sand or perlite into the substrate for proper drainage. Avoid clay or moisture-retaining soils. In pots, use cactus and succulent potting mix.
