This past winter, when the bushes went dormant, I transplanted my 3 yr old blueberry bushes from containers to my garden. They did great - lots of new growth in the spring, and one of them had lots of berries forming. I've noticed now though that some of the berries that were green, have sort of died or shriveled up. Short of testing my soil's PH (I will probably get a kit to test it though), does anyone know what might have caused this? there are still green berries on it, but not as many as before. When I transplanted, I prepped the hole to lower the PH - by adding pine needles, compost and some rhody/azalea fertilizer. I also mulched with wood shavings. They still look healthy and none of the leaves are dying or falling off. just wondering what might have caused some of the berries to not mature.
any ideas?
