Many domestic agricultural experts came to study the multi-layered coffee garden in Dinh Lac commune, Di Linh district.

As of April 2025, the 1-hectare Robusta coffee garden located on National Highway 20 connecting Da Lat - Ho Chi Minh City in Dinh Lac commune, Di Linh district has been cultivated for about 17 years according to green agricultural standards, with many layers of symbiotic plants supporting each other to purify the fresh air in the surrounding area. The owner of the garden, Mr. Trinh Tan Vinh, is over 60 years old, but is still passionately transforming the green garden that was created nearly 17 years ago. This has been recorded by reporters many times over the years under the green sky of the trees, flowers, and grass in the garden.

This time, continuing to sit for a long time under the shade of the trees and walking around breathing deeply with the multi-layered vegetation, the reporter did not have to spend much time to feel and confirm the story of green transformation as the owner of the garden Trinh Tan Vinh passionately said: "From the state of water loss in the soil causing drought, lack of humidity in the air causing plants to wilt and shock, up to now my garden has changed to a state of multi-layered vegetation, creating a gentle atmosphere and restoring the soil rich in moisture. Comparing the temperature in my coffee garden with multi-layered vegetation, the temperature is lower than the garden next door that is purely planted with coffee without a carpet of wild peanuts covering the ground and shade trees above. These two spaces are so different that it is like going from a cool, green, fresh dense forest to a stuffy area lacking most of the shade of trees and grass...".

The green transformation results of farmer Trinh Tan Vinh in Dinh Lac commune, Di Linh district are not only a research destination, applied nationwide, but have also spread abroad, and have been invited by international organizations to exchange solutions with farmers in one or two countries in the Middle East and Southeast Asia. Accordingly, Mr. Vinh shared that, let's change from "hoeing" farming to "cultivating" farming with grass, organic materials and microorganisms for a "healthier" environment. Thereby, most effectively protecting the beneficial microorganisms in the soil, creating an ecological protection function and a symbiotic effect with multi-layered trees in the garden, improving humidity and increasing the natural fertility of the soil...
