The Trellis That Wouldn’t Stand Up Straight
By the end of May the vines in the third bed had gotten completely out of hand, flopping over the side and trailing into the gravel path, and I finally admitted to myself that I should have built some kind of support back in April when I first thought about it. So on a Wednesday evening after work, with just enough daylight left to get something started, I hauled out a handful of scrap lumber and a roll of garden twine and decided the trellis was happening that week whether I’d planned it properly or not.
A Loose Plan
I didn’t sketch anything out beforehand, which in retrospect was probably the root of most of what went wrong later. My plan, such as it was, involved two upright posts sunk into the corners of the bed at the back, connected by a crosspiece near the top, with twine strung between them in a rough grid for the vines to climb. It seemed simple enough in my head, the kind of thing that shouldn’t need much more thought than that.
Part of the rush came from the fact that I was doing this on a weeknight instead of a proper weekend, squeezing it in after dinner because I didn’t want to look at another day of vines dragging in the gravel. I’ve noticed a pattern in myself over the years of these projects, the weeknight ones almost always end up with some kind of shortcut or oversight in them, because I’m racing the light instead of working at a pace where I’d naturally stop and double check something.
Getting the Posts In
I used my old spade to work two holes down into the soil at the back corners of the bed, deep enough that the posts would have something to grip once I backfilled around them. This part went fine, better than fine actually, the soil in that bed is soft enough after years of amending that digging was quick. I set the posts, packed soil back around the base of each one, and stepped back feeling good about how it was going.
Where the Lean Started
The trouble showed up once I added the crosspiece. The moment I screwed the top board across both posts, the whole structure shifted slightly to one side, just a couple of degrees, but enough to be obvious once I stood back and looked at it straight on. I think one post had gone in a little deeper than the other, or maybe the soil around one was packed looser, because the whole thing wanted to lean toward the shallower side the second there was any weight or pressure connecting the two posts together.
Trying to Fix It
My first attempt at correcting the lean was to pull the shallow post partway out and redig the hole, which helped a little but not entirely, there was still a faint tilt when I checked it against the fence line behind it for reference. I ended up doing what felt like a bit of a cheat but actually worked: I drove a short stake into the ground at an angle behind the leaning post and tied it off with twine, essentially guying the structure the way you’d stake a young tree. It’s not elegant. If you look closely you can see the extra stake and the line running to it. But it stopped the lean from getting any worse.
Stringing the Twine
Once the frame was stable enough to trust, I moved on to the part I’d actually been looking forward to, running twine back and forth between the posts and the crosspiece to make something the vines could grab onto. This turned out to be more fiddly than I expected, mostly because the twine kept slipping loose at the corners where I’d looped it around the post instead of anchoring it to a screw or a notch. I ended up going back out with a handful of small screws, driving them partway into the posts at intervals just so the twine had something to catch on and hold its position instead of sliding down under its own tension.
Living With the Wobble
Even with the stake, there’s still a small amount of give in the whole structure if you push on it, a little more flex than I’d like from something that’s supposed to hold the weight of a season’s worth of vines. I’ve decided to just watch it rather than tear it apart and start over, partly because the vines have already started climbing it and I don’t want to disturb them, and partly because I’m not fully convinced a rebuild would come out straighter anyway, given how the first attempt went. On breezy evenings I’ve caught myself glancing over at it from the kitchen window, half expecting to see it tipped further, but so far the stake has held its ground.
What I’d Do Differently
Looking back, the whole problem traces to skipping any real plan and just eyeballing the post depths instead of checking them against each other as I went. A five minute check with a level against both posts before adding the crosspiece would have caught the unevenness before it became a structural lean instead of a cosmetic one. I know that now. Whether I’ll actually remember it the next time I’m rushing to get something built before the daylight runs out is a different question entirely, and if the trellis in bed three is any indication, I wouldn’t bet on it.
I’ve also started keeping a level out in the garage instead of buried in a drawer somewhere behind the paint cans, on the theory that if the tool is easy to grab I’m more likely to actually use it instead of skipping the step because reaching it feels like a hassle. It’s a small change, but so was the lean in the trellis at first, right up until it wasn’t.
