My friend constructed this garden completely from pallets. She filled it with rich amended soil and you would not believe the crop she has harvested this year. For more details....check out http://www.thistlewoodfarms.com/the-pallet-t...
This looks great but I would caution people about growing edibles in pallets. I've read that they spray all sorts of stuff on pallets and you really don't know how "clean" they are because they are reused many times.
If anyone has back problems, like my daughter-in-law, this would be a good idea since you wouldn't have bend down. I have seen this done before and I would like to try it sometime.
Thisle, can you tell if the box if filled from the bottom up or if it is blocked somehow?
