Alchornea is a plant genus which requires a balance of care elements like sunlight, water, suitable temperature, and well-drained soil. These plants thrive in moderate to high light conditions and consistent watering, though care should be taken to avoid waterlogging. They are compatible with a broad range of temperature climates (10-35°C), and they prefer humus-rich, loamy soil. Common challenges include sensitivity to frost, pest infestations like caterpillars and aphids, and susceptibility to diseases such as leaf spot. Seasonally, they need more water during summer, while in winter, they require protection from colder temperatures.
