how deep rooting are courgettes?
hi, I've recently moved house and have inherited some rasised beds. But on digging one over I've found it is very gravelly after about a spade depth down and there's hard slabs (brick?) that prevent digging further in some patches/quadrants. I was planning to grow courgettes and sugar snaps here but now not sure. Sweet corn was another option. Too shallow? Should I try to build sides up a bit more? Or what would be better shallow rooting veg? Thanks!
