My homemade root barrier
I've used paving stones (flags) to create a root barrier. When I dug up
the garden there were tree roots just below the surface emanating from a row of trees that were planted about 20 years ago. Don't know what trees they are, but they are those fast growing evergreen types. Look a bit like Christmas tress. Anyway, the flag barrier is 61 Cm deep(2 ft)from the surface of the garden. But, between sections there is a gap between the flags of about 4mm or 5mm. QUESTION: Do I need to plug the gaps between flags, or will I be okay leaving the gaps? Thanks. |

I'm doing a similar thing on the allotment. I'm putting the slabs in alternate ways round, so that the ends meet nice and snug because of the chamfers. Another option would be to overlap the slabs. But I expect some roots will always find a way through unless you use concrete. Steve |

I assume they are "old" flag stones, otherwise why not use short pieces of "old" corrugated iron sheet which could be hammered into the ground. Could be cheaper and easier. Bill |

The roots will find the gaps with the greatest of ease. But running a sharp spade down every year should keep them at bay. They're probably Lawyer's Friend cypress: ought to be available only under licence, and to those who can prove they'll plant them at least a furlong from their nearest boundary. -- Mike. |
