Privet Hedge leaves brown and dry
I'm relatively new to gardening, but have noticed my 2m high privet hedge between me and the neighbour looks dead half way along. The rest of the hedge now has health new shoots coming but about 3/4 roots in the middle look very dry and have hardly any leaves. The leaves that are left are brown and crispy.
What should I do? Do I need to replace this section of can I revive my hedge?
