Yes but my practice up to date has been to keep the BC well watered but drained when in recovery from drastic pruning. I will only submerge healthy BCs. I believe that submerging BCs actually stress the trees. Healthy BCs will respond with vigorous growth, particularly in the root growth to try to stabilize itself. Non healthy BCs will struggle. This is only my opinion. Other BCs experts may differ from my view.
Once this forest is growing well, which I expect to be soon. I will submerge the forest.
