Greeneocharis requires moderate light, consistent moisture without waterlogging, and thrives in warm temperatures with well-draining, fertile soil. It faces common challenges like pests, including aphids and spider mites, and is susceptible to root rot if overwatered. During spring and summer, greeneocharis benefits from higher humidity and may need increased watering. In autumn and winter, reduce watering, and protect greeneocharis from cold drafts to ensure health and vitality throughout the year.
