I am taking a gamble and trying some blueberry plants this year. Normally blueberries do not do well in our alkaline soils here, but there is a researcher at CSU who has been studying growing them in containers. In his studies, he is using 2gal containers and a peat-coir-pearlite mix. And he seems to have good success. However he is doing his work for commercial growers and moves the berries into a GH for overwintering and forcing.
I was thinking that if one did not want to move the plants then they would benefit from a larger container, say a 10-15gal one per plant. What do people think, is bigger better here?
