Yen Phu Commune is the third largest farming area of four-season lemons in the whole district. In 2012, the total area of lemon trees in the commune stood at just 8 hectares. In 2020, the local farming area for this crop has been expanded to 35 hectares, with an estimated output of over 400 tonnes this year.

The citrus variety is easy to grow and bears fruits all year round. Each year, traders come to the local gardens to purchase lemons and distribute them to other localities such as Quang Ninh, Hanoi and Hai Phong. The price for local lemon has reached as high as between VND17,000-27,000 per kilogramme.

Amidst the complicated developments of COVID-19, local authorities have recommended farmers focus on intensive farming on the existing lemon crops, while limiting the expansion of new planting areas, in addition to encouraging traders to connect with major provinces, cities and industrial parks to expand the consumption markets of the fruit.
