According to the news articles above, Dole Philippines, who already owns pineapple and banana plantations in Mindanao, Philippines is considering growing blueberries. This is good news since this is an expensive fruit which would give more job opportunities in Mindanao.
I am expecting that blueberries would finally be available in local supermarkets. Right now, there are about a handful of stores in Metro Manila that sell frozen blue berries. In New Zealand its available in almost all supermarkets when in season.
