The box is built and it is 8 1/2' by 5 1/2'. Why cut lumber if you don't have to plus bigger is better. The lumber I used is leftover scraps from when the house is built. Am on rain delay right now but this is what I have so far. Note I can build the sides higher if necessary but it will eventually be fenced to keep the deer out once I plant. I am sure they would eat the potatoes as soon as they hit the ground.
Newspaper is down
leaf layer done
To be continued but not today. Too tired.
