Phyllanthopsis are tropical plants requiring bright, indirect light, moderate watering, and well-draining soil. They thrive in warm temperatures but are sensitive to cold. Common challenges include overwatering, which leads to root rot, and pests like mealybugs and spider mites. Seasonally, phyllanthopsis demands higher humidity in summer and less water in winter. Spring is the ideal time for repotting and fertilization, preparing the plant for active growth, while autumn signals a reduction in these practices.
