Barriers to block over-growth into adjacent squares
As a new gardener I adopted SFG with gusto. I have two beds in which I may have been pushing the limits. One bed has vining winter squash plants along an edge of the bed with the intent that the vines will trail over the path between the beds. The other bed has potatoes. The issue is that I have OTHER veggies in the beds next to the squash & the potatoes, and those other veggies were being crowded/shaded/overwhelmed.
I put a barrier into each bed to keep the wandering Big Boys on their side of the line. I re-used the stiff wire segments to form the hoops of a tunnel cloche earlier in the season. I put the hoops in along the line between the Brutes and the Victims, and secured some summer-weight row cover materials between the hoop and the ground as a sort of semi-circular panel. We'll see if it works.
