Growing Guide: Thai Guava
Growing Tips
Plant in full sun with well-drained soil, and water regularly to encourage flowering and fruiting. Guavas thrive in heat and humidity and are well-suited for subtropical climates. Feed with a balanced organic fertilizer during the growing season. Prune lightly after harvest to maintain shape and airflow. Hardy in USDA Zones 9–11, guavas can also be grown in large containers in cooler regions and overwintered indoors. Fruiting typically begins in 0-1 years for grafted (XL size) or 2–3 years (for seedlings) from planting, with abundant harvests that continue for decades.
