What is the general policy for paving around an existing tree? Is there an equivalent 'no-dig' option so you don't disturb the roots? I know we could deck round it but ideally we'd like to do a brick terrace. Any thoughts and advice would be much appreciated.
what is the diameter of the tree ?
I would pave up to about 12" round the tree (more if you can) and build a seating box round to cover the unpaved area.
if you pave right up to the tree it will move and lift over time and look bad
Thanks for your advice.
My understanding is that feeder roots are close to the soil surface and tend stretch out as far as the tree canopy.
Yes - that's what I thought, which is why I would be reluctant to excavate with in the RPA...just wondered if there was a cunning way of doing it without damaging the roots.
How about a tree grille and then paving? Loads of examples here http://www.google.co.uk/search?q=tree+grilles&hl=en&prmd=im...
if your brick round it but leave a square border edge about 12 inces then lay a thick gravel over the bare soil. to keep the weeds down but still allow water to filter thought to the roots.
have you considered resin bonded gravel ( http://www.pavingexpert.com/resin.htm )
or play ground safety matting (http://www.aileplay.com/Rubber-mats-ProductShow-1.html)
If you pave around the tree you stand the risk of:
1. disturbing the root zone = potential loss
2. by the act of paving cutting off the source of water and nutrients to the tree = Potential loss.
If you have to pave the area then do it and take a chance, the shallow root
system will be in the next garden as well, so it will probably be ok.
Just raise up the level so that you are not damaging the roots and leave an
18" gap around the trunk, -just make sure you do not raise the soil level around
Thanks very much everyone - I really appreciate the advice. I will take a view on whether it is worth doing or not.
