Tree root barrier

[caraellen]

I'm hoping to grow vegetables in a part of my garden which, unfortunately, is close to a Leylandii hedge (I don't want to start a dispute over who owns the hedge with the neighbours!). I heard that putting in a tree root barrier might help - does anyone know what I need to do and how far away from the hedge I can start growing my veg?

I haven't heard of a tree root barrier as such before but I assume it's a fairly solid barrier such as a sheet of galvanised iron or some large paving slabs in an upright position, which goes down to a depth of 18 inches which will stop the roots intruding in your growing area. Don't know how high the hedge is but I'd assume the barrier needs to be inserted about a yard away unless you're prepared to do some excavating first to try and remove some of the roots your side. (We're in the process of trying to dig out some roots from our neighbour's eldberry tree which is located immediately the other side of our fence. Some of its thicker roots have spread two yards into our garden). The other alternative might be to consider raised beds with extra soil added. contained by railway sleepers. I have a border beneath a shared fence in which I grow beans and tomatoes. My neighbour's side is full of shrubs about ten feet hight and their roots continually rob my soil of nourishment and moisture so be prepared to water often (possibly with an automatic irrigation system) and add an annual dressing of compost and rotted manure, otherwise your yields may be disappointing. Good luck. Let us know how you solve the problem.

you can use paving slabs if you have any but this stuff is made for the job

Out of interest I've just checked out the website Woofgang gave. Can anybody explain to me how the tree roots will be diverted as I would have thought that in time they would grow strong enough to break through the fabric (unless it's exceedingly strong)?. Has anybody used it and found it successful as it might be the answer to some of the problems I'm experiencing with roots of neighbours' trees and shrubs? Thanks.

you are going to have to look at this problem carefully...the hedge may be yours then you could trim it down..as its bound to block light which you will need for the vegetables..also the soil will be really dry near to the hedge..the only advantage of the hedge is it will be a good shelter against strong wind etc..cant you just ask who the hedge belongs to?then you would get some clarity on the situation..

Thanks for your advice, it's much appreciated. I think I'm going to opt for a barrier and raised beds to be totally sure.
