ðą How to Care for Century Plant to Prevent Aphids?
ð§ How to Water
Water only when the soil is completely dry â typically every 14 days in the growing season and once a month in winter. Never allow water to pool in the saucer. Overwatering causes crown rot, the number one killer of agave plants.
âïļ Lighting
Requires full sun â at least 6 to 8 hours of direct sunlight daily. Tolerates partial shade but growth will be slower and leaf coloration less vibrant. Indoors, place near south- or west-facing windows with maximum light exposure.
ðŠī Ideal Soil
Use cactus and succulent potting mix with excellent drainage. Combine coarse sand or perlite (50%) with potting soil (50%). Pots must have drainage holes. Ideal pH between 6.0 and 8.0. Avoid clay-heavy or compacted soils that retain moisture.
