I'm wanting to gauge everyone's know-how here and see if this is feasible. I'm wanting to build a veggie garden at the house I had previously done six 4x8 beds at my last house and that was plenty. I've read up on and love the idea of hügelkultur. At this house I have several areas I could do a walk in garden with raised beds. But then I thought...what if I just make one really long bed? I have a fence I just put up (split rail style with wire fencing behind so we can see into the woodlot behind us) and this particular section would be probably 75-100 feet. I'd make it 3 feet wide, 3 feet tall (for the hügelkultur plus no bending). The walls I was thinking corrugated roofing or the metal floor decking stuff, and whenever panels overlap there will be a cedar piece going in to the ground, maybe even link up with a cross piece to the other side for stability. I can still do crop rotations as I'd still segregate the particular crops in their respective spaces. One thing I thought of was one long row of corn along the back as well for decor and adding a foliage look to the fence.
think this is feasible? The only perennials will be things like kale, chard, rhubarb, potatoes, etc. the things that don't die off in Zone 8 where I am (Seattle).
Side note: I even thought about entrenching plastic totes with holes in them for in-ground compost bins spaced out every 20 feet or so. Toss kitchen scraps and brown matter in there year round to consistently feed the soil, but wasn't sure if that's even needed for the hugelkulture bit. Maybe it'll help for the first few years as the wood breaks down? And I know that fresh wood is best, but we have a large pile of who knows how old wood already split for firewood and we don't have wood burning appliances, so I'm tempted to throw those in there. I have time to plan, this won't be until next spring.
