Privet hedge black spots

Hello everyone. Ive read all I could, but can't seem to find the answer. Ive seen a lot of photos of different kinds of fungus. But they look different to me then my photos. What do you guys think?  They are newly planted. Less than a few months. They flowered nicely and looked great, then turned with black spots, thinned out, and now leafs turning yellow. Could it be over or under watering? Lack of nitrogen? Thanks!

    It's nothing to worry about about. Mine get it every year. The yellowin will be just old leves that have come to to the end of their days. 

    Mine do well on a feed of liquid nettle fertilizer once a year. You could feed yours a slow release nitrogen feed

    It could be a number of reasons. The soil when young should be free draining. The soil it's planted in should have been dug over properly and opened up if it's been compacted previously. Without a rain shadow, the young shrubs can struggle with excess wet. Once you have planted them, it's a good idea to put a thick layer of bark mulch to create a climate where it's stable and not allowed to get too dry or too wet around the base. The shrub will still need watering consistently for the first few years, until established, especially in the drier spells in summer time. You can snip off some of the affected leaves, just make sure you clean your equipment thoroughly and remove excess dead leaves regularly in the soil areas. I don't recommend feeding the plant yet.

    "...their as tough as old rope." unquote.  Thats as maybe but we dont plant, water and care for our hedges so we can have a view of 'old 'rope at the end of our gardens. How do we we get rid of this black/brown spot menace for good?
