I have a silver birch tree in my garden - two years ago we had it cut back by someone who possibly didn't know as much about managing trees as he thought. He cut quite a lot off in November of 2016 and last year (2017) almost no growth at all occurred - two "sprays" of very thin branches came out in two separate places and then died.
This year, at time of writing (May 2018) there is no live growth visible anywhere on the tree.
We don't know how old it is, as we moved into the house 4 years ago.
Is it dormant? Or is it dead? It's a lovely tree so I am reluctant to remove it if there's any chance that it might still be alive. Is there any way I can check that it is still alive or maybe even help it out a bit if there may still be life deep inside it?
We're in the UK, in the South if that helps.
