This post is about the whole process. It took five hours with an intermission. The tools are there, except the gloves. There are many gardeners of all persuasions, some are excellent, good and meaningless.
However, not many break concrete pavements to plant anything. In my case, it started thirty years ago in our mostly concrete back yard in Savarona, before the foreign occupation, in the Caguas Country.
During our four years here, I have dug five holes in the north where most vines are. Three in the east, plus the same procedure for 3 French drains in the south pavement.
A third of the hole was filled with the compost I collect daily. The sand left will be recycled for future projects.
That is that.
