I have an area of tarmac next to a public footpath. There used to be a
wooden fence but it was vandalised before I moved in and eventually
pulled down by the council (even though it was on my land). I'd like to
replace it, but don't much fancy the idea of digging up the tarmac to
put new fence posts in (is it as much work as it looks?) and fully
expect it would just be vandalised again anyway. The other idea I had
was to drill big holes in the tarmac and plant seedlings in the holes
to start a hedge, but I have no idea if this would work - how deep is
tarmac usually, and is there loads of hardcore underneath? Which idea
sounds least crazy?

I think I'd replace the wooden fence with a breeze-block/brick wall -
more difficult to vandalise and anything the little wonders do to the
other side won't bother you. The roots of anything planted through the
tarmac are likely to damage more of the tarmac around the hole.
