(HBO) – Previously, it took farmers in Lac Son district, Hoa Binh province, at least 7-8 years to take care of Doi trees (michelia tonkinensis) before harvesting their nuts which are used as a spice. Now, the technique of graft helps halve the time and opens up a new promising way of growing Doi trees for Quach Phien in Chieng hamlet, Phuc Tuy commune, Lac Son district.
A Doi garden is located on Roc Trau
hill,
500 metresfar away from the local residential area. With branches bearing with rich
fruits, we can’t believe the Doi trees in the garden are in the fourth year.
"We used to plant maize and cassava. Acacia trees also take a long time while
the profit was low, therefore I used to work far from home”, Phien said.

Grafting Doi trees opens up a new way to get rich for Quach Phien (L) in
Chieng hamlet, Phuc Tuy commune, Lac Son district.
It takes just three or four years for
grafted Doi trees to produce fruits while the traditional way takes seven or
eight years. This is a promising way, Phien said, adding that he learnt to
graft Doi trees by himself, with the successful rate now reaching 80 percent.
Fifty grafted Doi trees, which were planted
four years ago, are developing well. The land here is fertile and suitable for
growing Doi trees. They have flowers and fruits right in the third year. Last
year, Phien sold fresh Doi nuts at 600,000 VND (24 USD) per kilogramme, and
dried Doi nuts at 2 million VND (88 USD) per kilogramme, earning over 100
million VND (4,400 USD) from his garden. This year, the trees bear plentiful
fruits, and promise a same value, Phien said.
The Doi trees are developing well
among the Acacia forest. Phien is excited when talking about his Doi trees,
though he regretted for planting them a little too thick. Doi trees should be
planted seven metres away from each other to enable their branches to stretch,
Phien said, adding that he has planted an additional 300 grafted Doi trees and targets
to plant 500 trees this year.
To ensure the quality of grafted Doi
trees, Phien had to select those with many fruits and good development to graft
with other trees. His 50 four-year-old Doi trees offer a huge source. Seeing
his success, many local residents bought seedlings from Phien and now have also
well-developed Doi gardens. Phien plans to expand his Doi garden to supply for
the market.
Besides Doi nuts, Phien also raises
chickens in the garden and earns a stable income. Grafting Doi trees has opened
up a new way for Phien to get rich right in his homeland. This is a promising
livelihood for local residents as many have learnt from Quach Phien to shift
their mixed gardens to Doi trees.
Once a mountainous province facing many challenges, Hoa Binh has, after more than a decade of implementing the national target programme on new-style rural area development, emerged as a bright spot in Vietnam’s northern midland and mountainous region. In the first quarter of 2025, the province recorded positive results, paving the way for Hoa Binh to enter a phase of accelerated growth with a proactive and confident mindset.
Hoa Binh province is steadily advancing its agricultural sector through the adoption of high-tech solutions, seen as a sustainable path for long-term development.
The steering committee for key projects of Hoa Binh province convened on May 14 to assess the progress of major ongoing developments
A delegation of Hoa Binh province has attended the "Meet Korea 2025" event, recently held by the Ministry of Foreign Affairs, the Embassy of the Republic of Korea (RoK) in Vietnam, the Korea Trade-Investment Promotion Agency, and the People's Committee of Hung Yen province.
Hoa Binh province joined Vietnam’s national "One Commune, One Product” (OCOP) programme in 2019, not simply as a mountainous region following central policy, but with a clear vision to revive the cultural and agricultural values in its villages and crops.
From just 16 certified products in its inaugural year to 158 by early 2025, the One Commune One Product (OCOP) programme in Hoa Binh province has followed a steady and strategic path. But beyond the numbers, it has reawakened local heritage, turning oranges, bamboo shoots, brocade, and herbal remedies into branded, market-ready goods - and, more profoundly, transformed how local communities value and present their own cultural identity.
