Blueberry Disaster!!! Help No Leaves

Question

I live in southern west Australia and have begun growing blueberries. Soil acid correct and all seems full steam ahead. . . lovely flowers, healthy fruit, but no leaves and plants look like they might be on their last legs!! Any help welcomed.  It also gets plenty of pure Aussie rainwater, love, care and tenderness. . . yet no leaves!!

Answer 1

I suspect that the plants have a fungus. Treat the plants with a fungicide and try to prune a little to allow better air circulation. Also, if possible, water from below.
