Conifer Tree's Query

Hi,

I have a row of conifer tree's which I cut recently for the first time this year.

Before starting to trim them I found the middle at the top to look dead and wonder if its from me cutting them to serverly last year. See picture attached.

Would be good to understand my assumption is correct and confirm they can't be salvaged etc.

Thanks in advance.

 

Yes very likely , golden leylandii and most conifers can't regenerate when cut into brown wood . I wouldn't worry about the top as you can see the sides do tend to push into the open space , it will fill in a bit faster if you raise the height of the hedge a bit.
