ðą How to Care for Caribbean Agave to Prevent Sunburn (Sun Scorch)?
ð§ How to Water
As a desert succulent, Caribbean Agave needs very infrequent watering. Allow the soil to dry out completely between waterings â 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.
âïļ Lighting
Requires full sun for best growth â 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.
ðŠī 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.
