I decided to check on the apple trees that are still half buried, just to see if they were perhaps budding. And yes, there are some buds appearing on the ends of the branches.
Unfortunately I also spied two of the lower branches still in the snow had broken at the base. This is only on the tree closest to the shovelled walkway, so I don't know yet how the other apple or the cherry tree have made out.
I'm hoping that I will be able to repair the branches later. Something new to learn... I found some instructions here.
So far I'm not sure if there is any other damage, but as the snow goes down there may be things appearing.
