I have built a trellis using ground screws. The ground is not as firm as I would like, so the trellis wobbles when greater pressure is applied to it. I would like to stabilize the trellis without having to cast concrete plinths. My idea is to anchor the trellis to the skirt of my deck using a beam. The problem is that the deck and the trellis are not parallel to each other, and I don't think I can use a beam shoe due to the angles (See image).
What kind of fittings can I use to handle this, or do you have a better idea?

I would probably have built a planting box at a suitable height, as it camouflages the purpose of the support better. It fits perfectly in the triangle between, and it provides great support as well.
A planter box was a good idea if it was just in that place. I only took a picture at one spot to illustrate the differences between the deck and the trellis. The entire stretch is over 10m long and the distance between the deck and the trellis increases along the stretch, so unfortunately, planter boxes would be difficult.J Jocke Best said:
You might want to take a full-view picture so one can get an overview. A lot of beams getting longer and longer doesn't look nice either. For example, should one be able to walk along the gap? Otherwise, it's possible to build some form of elevated planting, steps, or the like, but it's easier with some pictures of the environment to be able to advise.
Well, it will be difficult with just a planter box there. Now you're probably looking for a simple solution, which I don't think will be so easy, but I would have placed 3-4 90x90 posts along the deck, into the ground and anchored in the deck, and then placed crossbeams for the trellis and created a bit of a pergola style if that's what you're going for. This way, you support the trellis and get a nice frame. If it wobbles, you can place a 45-degree brace in the corners.
