The polyalthia genus encompasses plants that typically require a balance of bright, indirect sunlight and moderate watering, allowing the soil to dry slightly between waterings. They thrive in humid conditions with warm, consistent temperatures. Well-draining but moisture-retentive soil is optimal. Common challenges include pests like aphids and mealybugs, and they are prone to root rot if overwatered. Seasonally, polyalthia may need protection from intense heat in summer and frost in winter, with reduced watering during cooler, dormant periods.
