How To Build a Better Trellis

In my garden, I use a sort of variant of Square Foot Gardening. It works well because of the fact that I only grow on approximately 400-500 square feet. My biggest difference is that I generally like to keep things relatively informal. Part of my logic behind this is that I like to "leave my options open" so to speak. I've found that in the garden, as with many other parts of life, if you follow too many rules (or perhaps guidelines is the better word) by doing it the way that the "experts" tell you to do it, you run the risk of missing the opportunities and flashes that are possible through experimentation.

One such "flash" came to me early last year and I went with it. The result, I think, is one of the best from any of my gardening technique trials that I've had and I thought that with a lot of people just starting to try and figure out what their gardens will look like this summer it was a perfect time to share it. What it is, is a trellising system that allows me to use my 4-foot-by-6-foot raised beds in many different configurations depending on the crop that I wish to grow there that particular year. In doing so, it also frees me from the chore of having to rebuild or move trellising apparatus every year, or worse yet every season, because it can be quickly tweaked to serve my needs. I've built one over each of my 4-by-6 beds and can either set it up as needed, or ignore it altogether and use the beds as though there were nothing there at all.

I put together a couple of renderings of the basic structure to give you an idea of how it's built. The ones I have in my garden were made largely from recycled 2-by-4s that I ripped in half to make 2-by-2s, although I did have to purchase a few. I joined them very basically with long grabber screws (course threaded.) and some corner triangles for strength.

Straight Configuration Trellis

Basically, it’s just a cube that’s been built on top of an existing 4-by-6 raised bed. The image above is of the system in a straight configuration. Across the bottom of the raised bed, I ran a piece of 1-by-2 scrap wood that I could tie twine off to and then ran that up to a third top piece that I added. You could actually run the string out to the edge pieces to support the top of the plants when they reached above the top of it as well. My beds are 6 feet deep, so I would run one string in the middle of each square foot to support, for instance, a tomato plant.

Great idea Paul. This will fit right in to my greenhouse/shadehouse project, and offers a solution to how to grow as much as possible in a small space. Even though I have ten acres and a large, fenced garden, the intense summer sun and scorching winds are a death sentence to most of my veggies. Not to mention the critters that like to nibble my tender greens.
