I had two blueberry bushes at my last house.
It seems to me that bluberries are about the easiest food to grow. It thrives in acidic, rocky soil and has few problems with pests and disease. Only problem is keeping the birds away...which is easily accomplished with a net over the bush.
One of the wonderful things about blueberries is how healthy they are - chock-full of antioxidants, pretty low-calorie, and low on the glycemic index, too. They’re so good I would eat them even if they caused cancer in rats, but it’s nice to know I’m doing my body a favor when I eat a point in one sitting.
