I have a problem with laylandii browning.

I recently cut what started out before its crew cut a green conifer
hedge row made of 12 x 11ft high conifers out front of bungalow
bordering a church, there now is a brown hedge after its hair cut. What
would cause the browning the six laylandii hedge row in the back garden
is fine. Both Conifer hedges are approx 40yrs old were here when we
moved in. 2004
Thanks in anticipation
There are two main causes of Leylandii browning
(1) cutting it back too hard
(2) an aphid that specialises in ruining Leylandii, not very common but
found here and there.
Given you have just cut it back, (1) seems most likely.
Whichever the cause, it never grows back green again in the area that it
is brown. If you have just a small patch, you can often bend other
branches over the brown area. If it is a big area, you are stuffed.

This is one of the several reasons why leylandii is to be avoided.
There are other more compliant conifers available, if you must have
conifer. Otherwise things like several kinds of berberis and cherry
laurel make a much easier to manage and pleasant evergreen hedge.

If they have to be removed you will find it easier if you leave around
6ft of trunk as that will give you leverage, so many people cut trees
off at ground level then struggle to get the stumps out.
But as Sacha said you can use the old trunks to grow other plants up,
very good for climbing roses. In fact you could plant climbing roses
into them now and then even if you do get some regrowth it will make the
"Hedge" more interesting.
