I just moved into a new house, and in the garden there's wonderful silver birch tree, about 25 feet tall (I'm guessing there).
It appears that it is/was a weeping variety, but it seems to have grown rather straight and perhaps taller than it was intended in recent years - perhaps due to bad maintenance, I'm not sure.
There are some pictures of the tree here: http://imgur.com/a/TDVV1
I would like to know how I should look after it, and if possible, how to recover its weeping shape. It still does have lots of weeping branches, just some (stronger, likely newer) ones growing straight up now as well.
I am no tree expert, but would like to know how to do this myself.
Thanks in advance :-)
