I have a blueberry tree but the berries that grow are very sour and have seeds in them. Is there a reason for this? How can I fix it? Thanks.
Sour blueberries are SUCH a disappointment! Hopefully you didn't (accidentally?) purchase a bush which purposefully produces tart or sour fruit. This article may help you: https://www.gardeningknowhow.com/edible/fruits/blueberries/sweeten-sour-blueberries.htm
