Blueberries – Smaller Fruit

Q: We are harvesting wonderful blueberries from our plants. But I have noticed that the first berries are very large and the later ones are smaller. Also the newer leaves are a light green with dark green veins. Is there something we can do to make the berries all larger?

A: I think you’re perfectly describing underfertilization. The first berries in a cluster are given most of the resources the plant has. But after a couple of these berries ripen, the plant has less energy to devote to the rest. Your observation that the leaves have green veins and yellow tissue is a classic sign of chlorosis: the lack of nutrients in leaves. Have your soil tested ( and follow the recommendations for fertilizing your plants.
