These days, villages in Mai Son and Thuan Chau districts and Son La city are in a sea of white coffee blossoms.  Like snowflakes hanging off branches, coffee petals flutter and waft their sweet fragrance through the air. Young coffee berries begin to sprout and form clusters on the trees.  Based on the amount of coffee flowers on a branch, farmers can forecast the year’s yield. The local coffee hills are now blooming and bearing fruit, promising a bountiful harvest. Coffee trees were first planted in Son La in the 1990s, and coffee has proven to be a key crop that brings stable incomes for growers./.
