Pararuellia is a diverse plant genus, requiring moderate care. Generally, these plants thrive in bright, indirect light and prefer well-draining, rich soil. Overwatering is a risk, and they favor a warmer climate, although they can adapt to slight temperature changes. Common challenges include pests like aphids, and diseases such as root rot if overwatered. They are sensitive to frost so it's crucial to protect them in colder seasons. Seasonal adjustment includes decreasing watering frequency in winter while ensuring they get sufficient light in all seasons.
