As the title says really.
I cut down this large bush (not sure what it was but it was around 15 feet high) down a few years ago as I wanted a border of Phormiums.
It keeps sprouting up from the trunk so there's clearly life still there. It sprouts up shoots really quickly so it gets in the way of the Phormium leaves.
I don't need to remove the whole trunk but how can I kill it off and stop it sprouting without damaging any nearby plants?
Would a copper nail do the job? I thought of pouring diesel into a hole but could that get into the soil and damage nearby plants?
I've just cut them down so the photos don't show the sprouts that had got to about 80cm tall and were forming a new bush!
