Tran Van Thinh's family in Cay Co Hamlet, Son Nam Commune, Son Duong District caring for the red flesh dragon fruit garden.

Tran Van Thinh in Cay Co Commune is a pioneer in planting red flesh dragon trees in the locality. In 2012, thanks to dragon planting technical researches on the mass media, he bought 500 dragon cuttings to grow. After two years, these trees started bear fruits. However, due to the low-yield Taiwanese dragon fruit variety, it did not bring him high income.

After visiting the dragon fruit growing model in Vinh Phuc Province in 2015, he decided to plant a new 2-hectare the Thai red flesh dragon fruit area. This dragon fruit variety has a deep red colour, thin skin, and sweet taste and produces more fruits. Since 2018, his family has harvested 17-20 tonnes of fruit per crop with the selling price from VND15,000 to VND27,000 per kg, earning over VND170 million each year.

The dragon fruit garden with more than 1,000 trees of Tran Van Khoi's family in Cay Co Hamlet is also one of the typical fruit garden model in Son Nam Commune. In 2020, his 1-hectare dragon fruit garden generated more than 8 tonnes of fruit with an average selling price of VND20,000 per kg, helping him earn nearly VND100 million. He said that growing dragon fruit does not need to take much care while the economic efficiency is 4 - 5 times higher compared to other plants.

Son Nam Commune currently has more than 13 hectares of dragon fruit, mostly in Cay Co Hamlet. Realising the development of dragon fruit trees can support local people step by step to increase their incomes, the commune has cooperated with specialised units of Son Duong District to provide technical guidance for farmers to plant and take care of dragon fruit trees according to organic production standards.

In 2021, Hung Thinh Cooperative was established in the commune, with 7 members participating in growing dragon fruit. It members have the opportunity to gain knowledge of dragon fruit tree planting and associate with factories in product consumption.
