My hazel prob is the opposite - planted whips 3 or 4 years ago and I'm wondering when we should try the first coppicing (not yet I know). Trees grow slowly here, so what size should the trunks be when we cut and how many shoots should we expect?
At the same time, we planted ash - that will go down the drain when the ash disease gets to us, so I will try your layering of the hazel to fill the gaps FiB
And while we're all here, should birch coppice OK? We chopped one down last year and nothing has appeared since, but maybe the pesky rabbits got them.
