You will have to work in stages, and probably have to slice the hession as you go as it isn't practical to pull it all up. I would do six foot at a time - slide the pebbles over and then cut the hession, the weeds underneath will be weaker than most and so pull up easily, and then replace the hession and pebbles. Winter is upon us and with any luck it will finish them off.
