The best time to plant asparagus is the eighth lunar month. After 6 months harvesting can begin, with the harvesting period lasting for 9 consecutive months. The advantage of asparagus is that its sprouts grow very fast.

The asparagus growing model in Thien Ke Commune, Son Duong District, brings high economic efficiency for farmers.

Since it was first planted in October 2016, the asparagus growing area in Thien Ke Commune has increased to over 4 hectares with 18 households participating in the model. Each household harvests at least 20 kilogrammes per day.

Asparagus is grown in the commune following organic standards. As the crop can be harvested within the day, farmers absolutely do not use any plant protection drugs.

Thanks to cleaner production, people also intercrop winter melon, cucumber and luffa in asparagus plantations. All products including asparagus and other vegetables are sold at clean food stores in Tuyen Quang City at a price of VND50,000 per kilogram.
