Removing leyland hedge - risk to property?
I'm planning to remove a 35m-long double-planted row of very
well-established leylandii (approx 30 years old) from my front boundary which is 4m from the front of the detached house (purchased last year), part of which was built 100 years ago with a sizeable extension added 15 years ago. This dense hedge was 10m tall until I cut the top off at the end of last year in preparation for the coup de grace. It is now 4m tall. Some of the trunks are 300mm diameter and I'm concerned about their root systems. How far are they likely to have spread in poor-draining, clay soil? And what, if any, could be the risk to the foundations of the house? Removing so many at once will presumably have a significant impact upon the soil structure and drainage. There used to be a drainage ditch along the front of them but this was filled in some years ago and surface water collects rather easily in heavy rain. Without the trees to consume a lot of it, I'm worried about drainage. Should I put in a soakaway? TIA. Simon |

Nor is the fact that some of the trunks are 300mm in diameter, (which in this double row case, may mean double the density of such trunks) The real issue is the clay soil and foliage cover of the trees and the fact that 4m is not really all that far away in such circumstances. Not only do they soak up the surface water, but also play a part in controlling the water table. When digging a large hole to assess the foundations of a building, a certain volume of water will appear in the hole having being released from under the foundations as a consequence of digging the hole. Reducing the trees, as you have done will help to minimise the effect, but I'd be inclined to reduce them even further this year (to 2m) and then next year remove them entirely. However, you would be best advised to get direct, on site professional advice As for creating a surface drain, structurally, that'll probably be more a matter of convenience for you in terms of your ability to use and enjoy the property.... unless off course your talking about volumes of surface water capable of washing the building away (-; Patrick |

My tree removal firm said they needed 4m to be able to pull them down and out complete with roots, with tractor and chains.
