My garden needs a new fence as well as two new fence posts. There is an existing concrete base along the boundary which is already securing three posts and has holes where two posts snapped in the wind at the base.
One of the holes is intact with all four sides:
The other hole appears to have one of its sides broken, you can't see it from the following picture, but there's no sign of it when poking into the ground at the base:
My question is two fold:
What tool/method should I use to dig out the old debris/wood from the snapped fence post? It's obviously a tight space and I suspect I need to work smarter not harder.
For the hole that has one side of the concrete missing - what could I do to sure up the hold? Should it be relatively easy to lay more concrete around it? Or is there some other method of securing it I haven't thought of?
