I don't have a whole lot of space to garden, so I try my best to make the most of my vertical space using trellises and other structures. We're also renting our space, so nothing can be too permanent. I've designed my whole garden to be able to be taken apart if we need to move - we'll undo the raised beds, and the grass that is seeded there will be so healthy from my lovely garden soil. I say that as a preface because there are other great options out there, but for us it is most important that they work well, are cheap, and are easy to remove when needed.
We work with bamboo poles and twine, for the most part. This year we wanted to do some low tunnels over our raised beds, so we bought some PVC pipe and rebar stakes. We cut them too big last year, but that worked in our favour because I am enjoying using their length for trellising. In the above photos you can see my twine and PVC archway (left) that I have peas growing up one side, and cucumbers and squash on the other. In the photo on the right is a square trellis for peas that I made by weaving thinner bamboo stakes (6 ft. length) and leaning it against the wall. You can see it more fully in the photo below.
The above photo is a bit cluttered, but it does show what the garden actually looks like on a day to day basis - not just when I take a beautiful photo for Instagram! You can see my potato tower here, which I am still enjoying using. I've actually added another bin to grow potatoes in this way since it worked so well. I've got some chicken wire for things to grow up, and the long line of poles and twine is something I am trying for tomato supports. I've seen a lot of people use farm fencing for this, so I sort of made my own thing using six foot hardwood stakes, bamboo poles, and twine. The stakes are drilled into the raised beds, and the poles are keeping each tomato plant upright. The twine running between them keeps everything together and strong.
We're also using plants as trellises - I put in a lot of sunchokes this year, and I've got beans planted below to climb them. I've done the same elsewhere with sunflowers. I'm hoping the corn will grow tall enough to help some of my beans out as well, but I've got some other supports ready in case it fails me again this year.
What are some of your favourite ways to use the vertical space in your garden? I'd love to hear all about it in the comment section!
