Hey everyone! I'm diving into square foot gardening this year after about five years of gardening experience. I love the idea of keeping a grid system for my metal raised beds throughout the growing season since I worry I might get overwhelmed without it. I'm wondering if anyone has tips or tricks for maintaining the grid in metal raised beds? I'm thinking about using twine, but I'm unsure of the best way to secure it. I've read suggestions about using stakes, but I'm concerned about how stable they'd be with my loose soil. Also, I've seen the idea of using binder clips to hold the twine down, but I can already picture myself constantly bumping into them and having to fix them up. If you've devised a system that works or have any images to share, I'd really appreciate it!

I've tried the twine approach, and while it's nice at the start with tiny plants popping up, you forget it's even there once everything grows in. Personally, I found it more of a hassle than it was worth.
Last year, I used some old yarn from my knitting supplies. I taped it to the edges of my metal beds, and it held up all season until I took it down for winter prep.
Bamboo is a great option! Just lay it down in your bed for a quick and natural grid.
A few years back, I found a cool solution! I got a sheet of white, woodgrain PVC and cut it into 1.5" strips. I drilled holes every foot and used machine screws to hold it together. It looks like lattice, is weather-resistant, and I can easily put it up or take it down as needed—it even folds for storage! It's been one of my favorite methods so far.
I use a grid watering system as my guide! You can find them pre-made or make your own. I bought mine a while back, and it’s been great for the last two seasons. Occasionally, I just need to clear a few watering holes, but that’s super easy and hasn’t been a big issue at all.
Oh wow, I never considered using tape! That could really work for me.
