Veg plot project

Yes, the laurel hedge and drive are ours. The veg patch is accessed through a gap in the short leylandii hedge from our back garden. The drive is approx 3' higher than the veg patch area due to the land sloping. The laurel does need a trip back on the veg plot side but quickly gets in to thick stems in the middle and I've been concerned that if I cut it too hard back it wouldn't sprout from the thickest bits.
I may just have to be braver with it.
