Growing blueberries in wine barrels
I'm looking for some large wine barrels to transplant our blueberries from smaller pots. Is there a way to preserve the large wooden barrels for long-term growing, such as lining with a large plastic trash bags with drainage holes punched into the bottom? I would prefer the wooden barrels because I love their natural appearance and larger size, but don't want to have to replace a rotting barrel every few years, and blueberries need a LOT of water.
Has anyone had success growing blueberries in the smaller plastic(?) wine barrel look-alikes seen at the big box stores?
