Replacing a leylandii hedge
This is my first post and I'm hoping that someone, somewhere may be able to assist with our dilemma.
Our house sits on a hill above a relatively busy road which is currently screened by a fairly scruffy looking leylandii "hedge". It's seen better days and we're keen to replace but the siting of the hedge, the height required, congenital laziness and budgetary pressures aren't producing an easy answer.
The hedge sits atop a 15ft sandstone wall and runs east-west for around 40m. Given the location, I'm not keen for anything with the kind of root system that will push the wall apart and dump sandstone blocks onto unsuspecting motorists.
We're in the High Weald so the soil is fairly moist yet free draining.
Yew would be first choice but cost means we'd be buying relatively small plants and am concerned at the amount of time it would take to establish itself to the kind of height required. We do have the ability to nurture the saplings elsewhere and transfer once they've reached a serviceable size but I'm not sure how easily they transplant. Holly, rhodies and blackthorn also appeal but would consider anything other than the elder, bramble and leylandii jungle we currently have.
Any advice or food for thought very gratefully received.
