Since 1983 Mr Yu started the cultivation and then his son changed the course and applied less herbicide and fertilizer to make products residue-free. Now the grandson, to create a triple win condition for customers, producers, and the environment, starts the management from ecology. He only weeds by human effort and applies natural cycle to protect his fruits. The eco-enzyme and the compost made from the fallen and cut branches can be returned to the soil. In addition, there is citronella whose extracted oil is effective to expel bugs. The eventual hope is to let customers be comfortable with and confident in us.
