The box I cobbled together from old pallets, dirt is a mix of potting soil and local dirt spiced with chicken poo.
For the more observant viewers, you may notice that the closest 'V' is slimmer than the upper square -- the pallets were a little short. I plan to plant smaller vegetables in those areas.
@Vertelleus It's a form of gardening I didn't see for decennia. Never raised beds. Never planted on spacing required. If there is a gap in the bed, I plant something in it. Plants love companions and I just look on the rules of mixed culture. A bed is never empty, when it is cleared I sow or plant something at once.
