When is the best time to move a silver birch to a new spot in my garden

You should move it when it's dormant, in winter. Now is not a good
time. If you do decide to move it, make sure a nice big hole is ready
for it and take as much soil around the rootball as you can. However,
unless this is a special present from someone they are, as Nick says,
not that expensive and you might be better off starting again with a
new tree.
