Ruby guava gardening has proven to be a lucrative venture in Vinh Long province's Long Ho district, with each tree yielding 4-5 tons and generating a profit of around 50 million VND per year. The fast-growing tree starts producing fruit approximately 8 months after planting. It requires minimal investment, few pests and diseases, and minimal care, including adequate watering, branch pruning, and sufficient fertilization. The fruit's unique taste, crispiness, and beautiful color command a selling price that is 1.5-2 times higher than regular guava.
