Alniphyllum, a deciduous tree genus, typically requires filtered light, moist but well-drained soil, and moderate temperatures. Its care can be challenging as it's prone to insect infestations and fungal diseases. Alniphyllum is sensitive to harsh environmental conditions like draught and extreme cold. Seasonally, it needs protective measures in winter, increased watering in summer due to heat, and careful checks for pest activity in spring and autumn.
