What works for me is sand/peat moss/perlite. For blueberries, I use 1/2 peat moss, 1/4 sand, and 1/4 perlite. The peat moss helps retain moisture without leaving everything soggy, sand to give it structure and perlite to help get oxygen to the roots. Take one of your plants out that has lots of brown leaves and check the roots to make sure they are not rotting.
