When I installed a semi-permanent hosepipe on the plot, to save faffing about coiling/uncoiling it every time I wanted to use it, I carefully threaded it through the base of the hedge out of the way.
Well, that was the plan. Just about every time I cut the hedge I also cut the hosepipe.
Hedge looks great. Hosepipe doesn't. It's a good job they're easy to repair.
Memo to self - take more care next time!
