    Grow this shrub in USDA plant hardiness zones 7 through 10.
    Like other ericaceous plants, this tree does best in acidic soil. It can also tolerate a neutral pH. You can make your soil more acidic to some degree as needed.
    I would start with a soil test and ph test to check your soil nutrients.
    Then you can make adjustments to help you achieve those fruit!

    It appears to be a leaf fungus disease, anthracnose, or fungus-like pathogen, Phytophthora ramorum or other.
    Severity will be related to how much of the foliage is affected and if it is causing branch dieback or not.
    If it is affecting a small percentage of the foliage, or if it just on the older leaves, underside shaded leaves, then it may natural senescence and not of grave concern.
