Fencing Around TPO Tree

[Paddy1000111]

+1 for metaposts. They seem last longer than concreting them in anyway plus they can either move around (or through) small roots. Another advantage is if they do rot (or rust) out it's a nice easy job to put new posts in!

I don't know what sort of fencing you have been involved in but root protection aside met posts are purest dogshit and do not last as long as a decent 4" post that has been properly installed. Also believe the OP said concrete posts they will lean all over the shop on met posts.

This is interesting. Does it take a long time to airspade the holes? What depth can you get down to? Or do you just do the surface layers where roots are most likely to occur?

We go the full depth of the hole where possible, usually 60cm. Width wise we try to excavate a 30cm hole for the posts to be concreted straight into, that way there is no extra digging by the fencing crews. We start at the ideal post location and move to the left or right until we find a suitable root free area for the posts. 

 

Sometimes this works great and other times, you end up with a long looking trench of varying depth till you find a suitable place.
