Just a few more plants to go on the top tier, then need to top it all off with some rocks... :) Starting to plant the back of the next tier down; this time, i'm going to mark out and measure (!) the border and do some math *before* i start ordering the wall blocks. ;) (and this is where the slope starts getting steeper; i'm going to need to get a whole bunch of sand to backfill it before i start planting any further out from the back wall...)
