New boxes are built

Finished building the new boxes on Sunday. Painted them with boiled linseed oil this time to see if that will extend the life of the wood a bit. I still have to dig the boxes in and level them.

Also picked up my first load of manure (13 bags). Need about two more loads of that to fill the new boxes.

Also realized I have a bit of a problem with my layout plan. I have two adjacent 2x8 boxes running East-West. Directly in front of these is another pair of 2x8 boxes. The north side of all these boxes will have trellises. I was hoping to space these 2 feet apart, but I'm now realizing the trellises of the front boxes may shade the back boxes at certain points of the year. Trouble is, I need the boxes fairly tight to each other to save space, but I also need the trellis space for tomatoes, beans, cucumbers and peas. I'm wondering if 3ft spacing will be enough?
