I tried growing some Jewels a couple of years ago in a raised bed filled with a mixture of topsoil and pine bark, which is supposed to provide the acidic spil blueberries like. They grew for a few months, produced a few berries, then declined, turned brown and died one by one. At a total loss as to what happened but I give up on any further attempts. Additionally, what berries they produced were snatched by birds just as they ripened. How can you grow berries when the birds swipe them?
