A word or two about walls.
I used to be fond of the Motherpeace tarot, though now I see it as flawed in a fundamental way, hostile to the masculine as inherently toxic. That said there is much about it that is beautiful, and there is wisdom in that card.
I think a garden should be a sanctuary, a place where all the troubles of the world dissipate and nature simply is. A fence can and does facilitate that.
As a farm dweller I think about walls and fences constantly. Without them we couldn't function here. Hedges, screens, and windbreaks are also crucial. In garden design, barriers whether structural or visual, make a space seem much larger than it really is. Walls are good things! Thanks for pointing this out.
I love a good wall, as long as it is good in both structure and purpose.
