Any thoughts on the best way of putting up 4" * 4" fence posts (in a
sheltered city garden).
1. Treat posts with creocote and bed in concrete, (approx 18" in
concrete?).
2. Use metposts, those square metal containers with a spike at one
end.
3. Other?

Also, is it better to use fence posts with slots in the side which the
fence panel slots into
OR
just ordinary posts and keep the fence panel in place with galvanised
nails?
