What's going on with this BlueBerry?
This Darrow Variety Blueberry I planted last spring and it kind of just sat there but looked healthy enough. This spring it took off and then about a month ago it just stopped and has gotten progressively worse. In the last two weeks the number of yellow leaves have doubled.
It's planted in a good soil mix of bark and peat and has received two applications of ammonium sulf and one of miracle grow this spring/summer. What's weird is all the plants on either side of it are doing well.
