I planted smaller squash and melons without a firm idea on how I was going to trellis them. Going online, I found several references to using metal concrete reinforcing grids as trellis material. I knew immediately this was a good solution that would easily integrate with my T-posts, which I use for most of my trellis frames.
I found the grids at Home Depot where they are referred to as Remesh Sheets. They are less than $8.00 each for a 42 inch by 84 inch grid made up of a fairly heavy wire laid out in 6” x 6” squares. The quality of the sheets in the store varied and all were rusty, even though stored inside. I had to pick though the stack to pull out nice flat ones with no breaks in the wire.
The trellises were very easy to set up. After laying out my tentative spacing, I just pounded in the first T-post and laced in the grid using jute twine. I used some spring clamps to hold the grid in place while I laced the grid to the post. Using the untied edge of the grid as a guide, I pounded in the next T-post, clamped the first and second grid to the new post and laced them in together. From this point, it’s just a matter moving down the line with as many grids as you want to use. It’s a very simple process.
Several of the online setups I looked at used wood posts for framing set up as a sloped A-frame. I think the T-posts, being vertical will allow for easier weeding and harvesting with enough space to get to both sides of the grid easily. The T-posts are also easier to work with than wood.
My T-posts are 90” long driven in about 18”, so six feet above ground. The mesh is seven feet leaving about a foot of unsupported grid. I think the wire will be strong enough to hold anything that climbs up that tall without folding. We’ll see.
