Beech Hedge Roots in Raised Beds.
Hi, I am trying to protect a shed from the wind and rain by planting a Beech hedge. The problem is I can't find much information on the roots of these hedges. I'm brand new to gardening too so just starting out with the layout and borders of my garden. The hedge would be in a raised bed that is two sleepers deep and sits against a 9" thick wall that drops down 3' to the shed base. Can any one advise if the roots of this hedge would eventually break the bed or the wall?
If its not a suitable hedge could any one advise on another that would be fit for purpose?
Looking forward to hearing from you all.
