Happy trees requires partial to full sunlight and a well-draining, fertile soil. Optimal growth occurs in a warm, humid climate, avoiding temperature extremes. Regular watering is necessary, but soil should dry slightly between bouts. Gardeners face challenges such as root rot, leaf spot, and pests like aphids. Seasonal adjustments involve reducing water in winter and monitoring for frost damage. In summer, happy trees may need protection from intense heat. Regular pruning is beneficial to maintain health and aesthetics across seasons.
