The Greater Gardening of 2026 – Part 17 – Towering Trellises


I concentrated on increasing my ability to grow things vertically in several ways this year. I already mentioned some in passing, but let’s write specifically about just that.

I completely reworked the supports for runner beans near the south wall of my house. Instead of running the clothesline in a zig-zag fashion between the rain gutter and the poles at the bottom, I run it in such a way that each pole has only one clothesline running to it from a wire support on the gutter. The wire supports also serve a secondary role of strengthening the gutter laterally (it got bent out of shape by heavy ice and snow). I also increased the number of plants that can be planted there, so hopefully, I will get bigger harvests and a better coverage of the wall against the hot summer sun.

I repaired more of the old aluminium fencing that my father used to keep poultry in check. I used it last year as a trellis for butternut squash, and I am trying to do the same this year. Growing butternut squash vertically allows for denser planting of the plants and thus better use of space.

Unfortunately, all my butternut and hokkaido plants are rather pathetic. I was away from home for three days, and I did not want to burden my nephew with having to drag them indoors every evening, so I left them in the greenhouse. And as bad luck would have it, it was exactly those three days when the weather was so cold that even in the greenhouse the temperatures fell below 10°C. As a result, all my winter squash plants are yellowish and sickly looking. But I got them outdoors a month earlier than last year, and most of them are starting to grow healthy green leaves again, so they might not be lost yet.

I also had several aluminium frames approximately 180×90 cm in size. I repaired them, and to convert them into portable trellises for beans, tomatoes, and pumpkins, I covered them with PVC-coated welded wire fencing mesh.

I made 12 of these portable trellises, and I hope they last me for years. This year, I intend to use them mainly for an improvised shelter and support for tomatoes, because I have more tomato plants than fit into my greenhouse, and I do not want to throw them all simply away.

To finish the post, have a look at some very nice Aquilegia blossoms.
