Dillenia, belonging to the family Dilleniaceae, generally prefers a tropic environment with well-drained soil, high humidity, and plenty of sunlight. The plants require regular watering during dry periods, but can tolerate slightly drought conditions. They prefer a consistent temperature range of about 13-27 degrees Celsius. Common challenges include susceptibility to pests such as aphids and scale insects, as well as diseases like leaf spot. Dillenia may also be subject to wind damage. Seasonally, the plants require extra attention during prolonged dry spells in summer and may need frost protection in winter.
