I planted a hydrangea earlier this year, which was thriving – lovely dark green foliage & growing rapidly. Since the start of our ‘summer’ it has started to be effected by, what looks like, mildew. It has started to turn a pale yellow and is losing its leaves. I’ve treated the mildew with a baking soda solution however the shrub is still failing, badly!
