I don't think I have made a picture post here so I thought this would be a good start. I decided to try my hand at Blueberries and see if I can get them to grow in containers. Hopefully they will because I don't have the time to build raised beds for them right now. Species are: toro, sunshine blue, sci name unknown, self pollinating unknown variety and an earliblue They are 55 gallon barrels cut in half with 8 half inch holes drilled about an inch above the bottom.
I think your blueberry arrangement looks very promising. I hope they'll give you a bumper crop! We've got two bushes in the ground. I want more of them but never thought I might grow them in large containers.
