It's in very poor, heavy thin soil, with, (I suspect,) most of the roots heading under a concrete pathway.
Should I be slicing a spade along the edge of the pathway to get some closer feeding roots happening? If I do that, should I give it another year and do some slicing elsewhere during the growing season?
Any suggestions that I probably haven't thought of?
The hedge is around 600mm high... and there are around 8 trees in it, so it's not a massive project, but I would like to save as many as possible!
Then I'll plant some Melaleuca linariifolia (claret top) there instead.
