Building Raised Beds

We’ve been building raised beds for the high tunnel. They’re simple to put together, rather plain looking but efficient. Gardening is a marathon this year, not a sprint. I’m not sprinting from season to season to grow enough food, not this year and maybe not ever again. There are ten beds in the high tunnel, about 320 square feet of growing space, and only two of us to feed. I think once we’re done building raised beds, filling them, and amending the soil (that’s a story for another day), we’ll have more space than we need.

I’ve had to pull out plants that were still producing moderately well in late summer or early fall to amend the soil and plant for the fall and winter. With ten beds I think I’ll be able to leave the plants in as long as the temperatures allow. I’ll use other beds for fall and winter crops.

Two 8″ boards total 15.5″ in height because an 8″ board isn’t 8″ wide. It’s a new math thing. Remember “new math?” If so, you’re probably at least as old as me. Anyway.  We’re going with 15″. I knew I wanted two frames that are 15″ tall so that I can grow carrots and other long roots. Steve made the corner posts 15″ for all of the frames with the exception of one. We didn’t want to buy another piece to cut four sections. It’s a short bed and will be used for greens. Two raised beds are 15″ now and the rest can be by simply screwing the new boards on.

Supplies for a 4′ x 8′ x 7″ Raised Bed Frame

For one 4′ x 8′ x 7″ high frame you need three 1″ x 8″ x 8′ boards, four 7″ long 4″ x 4″ posts, and eight 3″ wood screws.

I screwed the end boards into the 4″ x 4″‘s on the back of my truck to cut down on the amount of bending I’d have to do. The raised beds are to alleviate some of the wear and tear on my bad back.

An 8′ board is cut in half to make the end pieces. It takes seven or eight minutes to put the frame together. Later,  we’ll add the top boards but for now this is fine.

Do you use raised beds? We’d love to take a look at them if you have them in your blog. Please feel free to leave a link in the comments.
