Watercress is only fresh when planted in areas with clean water. If a small part is covered with soil or polluted water, the plant will turn yellow and die.
Residents of Gio An commune (Gio Linh district, Quang Tri province) plant watercress using water from a 5,000-year-old ancient well (Champa Kingdom era).
It can only be planted in areas with clean water sources.
The fresh water springs of Ong Well, Ba Well, Gai Well and Tep Well help the people of Hao Son hamlet maintain up to 7-12 hectares of watercress. Due to this huge advantage, Hao Son vegetable can fetch a higher price compared to prices elsewhere.
Watercress is planted on rocky, watery ground. In the dry season, in areas inaccessible to water, watercress will gradually die. So, in September, people who have rock fields located near the old well will raise watercress to sell.
It is harvested from October to March and sold in bunches costing five to seven thousand VND. Residents earn several hundred thousand VND per day.
“Watercress is easy to plant. All you need to do is plant seeds in fields with clean water flowing through them. After 15 days, we will harvest them. Watercress does not need to be fertilized. If the stream is polluted, the plant will die,” said Ms. Le Thi Linh from Gio Linh district.
Tran Anh Tuan traveled from Dong Ha town to the area to buy watercress. “My family members love fried watercress with pork. Every December I come here to buy 20 bunches of watercress. Other people also ask me to buy some for them.
Nguyen Van Song, chairman of the people’s committee of Gio An township, said, “Due to the Covid-19 pandemic, residents have had difficulty transporting watercress to markets in Quang Tri town for sale. sell it or transport it by train to neighboring provinces. With the unique system of ancient wells, we want to improve the quality of life of residents through tourism.
Watercress thrives on rocky fields with water from old wells.
