Hi

I am looking for some advice.

We have some silver birch trees growing on some waste ground at the rear of
our garden, they have now grown to such a height that they are spoiling our
view.

I don't want to cut them down however I would prefer that they didn't get
any bigger, in fact I would prefer them to be 6'to 10'smaller!!

Question is, if I go up with a ladder and just cut off the top could this
kill the tree? Will this stunt its growth? Is this the right time of the
year?

Any advice or comments welcome
