I'm pretty well decided on using those 'Metpost' things to secure the
4"x4" corner uprights of a pergola in the flower border around my patio. I've never used these before and I'm wondering how easy/difficult it will be to get them in *straight*? Is there some clever technique or tip to achieve this please? Or is it just a matter of trial and error - clobbering it with a large hammer and checking every couple of times? Should I first dig out (and then recompact) the area first to discover any obstacles, roots, etc?- posted
