Container blueberries were growing great...
I recently added two blueberry bushes to my container garden, One is of the Tophat variety and the other is a patriot(I think). I read multiple suggestions and was told by the vendor that a 2/2/1 Sphagnum peat moss, coconut coir and perlite potting mix would do well. I was also told to use Hollytone for fertilizing and to mix it in according to instructions.
This seemed to work well, as soon as I transplanted them in April I had tons of green growth. Two months later it has stopped. There are no signs the plant is stressed or being over watered. Leaves and all look healthy. It just stopped growing.
Can anyone help narrow this down? Could it be a PH issue? Should I go ahead and try watering it myself with some vinegar added?
