Blueberry Leaves Brown
I've had my blueberry plants for three years and each year the leaves turn brown. I'm pretty certain it is not lack of watering as this happens even when we get lots of rain. I get berries but not much. The foliage isn't full like it should be.
This year they are in pots (because of work being done to the house). They will be transplanted back into the ground in fall. In previous years I've had them in raised beds mixed in with lots of peat. The soil acidity was 5.5 a few years back when I planted them. I haven't tested since but do add sulfur each fall.
There is one blueray, one patriot and one jersey.
Any help is appreciated!
