growing blueberries in containers in the ground
I plan on using 55 gallon drums(from dairy farmer) cut in half and sunk in the ground and am wondering about the drain holes location. Since they will be about 17 inches deep could I put the holes up the side a little to use them somewhat as a self watering container or is bottom drainage holes the only way to go. There is good soil drainage otherwise. Can hardwood mulch be substituted for pine bark mulch it I can't find any pine bark mulch? Peat is easy to find so that won't be a problem.

I would put small holes or slits in the bottom to avoid water logged soils at the base of the container. You won't get much drainage besides the free water in your container because of the difference in pore size and the gap at the container. Hardwood mulch is fine (avoid black walnut).
