Why have my conifers going brown

[JoeyLin]

Absolutely no idea...
They have ALWAYS been green. i just pruned them (took them back about 4-5 inches), and they were all very green when I did so.

Now about 3 weeks later I am seeing brown patches for the first time ever in their lives. The other side are worse.

The only thing I havent cut is the top (last cut two years ago).

When i google it talks about not cutting back to brown... but these are just the leaves.

No green growth, and the tree dried out too much, inside is dead? I just asked dh and that's what he said..

I'd trim the tops and see if that makes them send out new growth further down.

Mine are brown but I accidentally burnt them with a bonfire 😀 not helpful I know

There's a lot online how these don't grow back from brown wood. But i wonder if this is different as it's just the "leaves" that have gone brown in parts since cutting. I didn't cut to the brown

Maybe I'm wrong but beneath the green on all conifers usually appears "dead". What is important is I didn't take it back to those branches. It was all green after I finished. Just brown patches appearing now. I'm hoping it's a summer thing and now some wet weather helps. Id be gutted to lose these. There's a main road on the other side

It's a tree's natrual habit (and this is what they are, although you are growing them as a hedge) to jettison lower branches in favour of those growing higher up, and I think this is what your hedge is doing. You've left the top, so all the energy is going into the upper areas and it thinks it doesn't need the lower branches any more.

My advice would be to prune the top now, and see what happens.
