Since that picture was taken I have come along quite a bit, but I will be very impatiently waiting for next Friday when they are coming to install gutters along the front windows, so my cacti will not be subject to cascading waterfalls in the summer! That is when I can start planting in earnest.
My major achievement of the day was to get the big Barrel Cactus in place, with a few smaller ones to keep it company. It's on a small elevation.
