That’s a solid framework. I’d start by cataloguing each plant’s growth rate, spread, and what it brings to the board. We need to lay out the squares so that every “move” is supported by the next one and the weeds don’t get a foothold. Keep the layout symmetrical so you can anticipate risks. If you want a touch of variety, pick a few companion plants that still fit the pattern. Just make sure nothing disrupts the overall strategy.
