how 2 sink pergola posts into DG patio without making a mess?
Hi, I'm about to create a decomposed granite patio and, in a month, I will be building a pergola to provide shade for the patio. The posts for the pergola need to go inside the patio. Should I dig the post holes for the pergola before I lay the decomposed granite and base rock? OR how do i create the holes after the fact? Thanks!
