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!
I'm wondering what the best hedge would be for screening? I've been thinking of Laurels, but believe they're an invasive species? I'm looking for something affordable and hardy & evergreen. In addition, I want to get this done ASAP so something that can be planted year round (or late Spring). It's for a border area of approx 5ft depth.
