Ok. In order for the arch to be higher, the tanks would need to be much closer together if you put them on the inside of the panel. They might be hard to get between, to weed, etc. So I would suggest you put them on the outside of the arch.(one on each side). I don't know if you considered that already as the option and pretty much have the tanks where you want them, but it looks like you wouldn't be able to weed the tank on the right, if it is right near the fencing. Have you put any drainage holes in the bottoms of these tanks? Don't put too many in. I was using about 9 food-grade stock tanks and put waaaay too many holes in them and the water would drain out much too soon, and I have to water them about every other day......which is a drag. I've tried to plug some of the holes and they're doing a big better. But mine are up on some cement blocks, and not right on the ground. I love trellis gardening. I grow (in the ground) cucumbers on both sides of the trellis and they love it. I also use my kids old swing set with fencing up one side and over it and grow winter squash, and it seems to love growing upwards.

What kind of "trellis" are we talking about? Stakes? Cattle panel? Real cages or the 3 ring type things? All the plants on your list with the exception of Health Kick would benefit from a 6 foot stake or cage. Jung's Wayahead, the determinate variety, easily gets to 4+ feet in my experience with it. And despite what your seed packet says, Early Girl, unless you bought Bush Early Girl, is a big indeterminate. ;) Big Beef Hybrid, Big Boy, the Brandywines, Caspian Pink, Pineapple, Red Brandywine, Yellow Pear, Beefsteak, and the Cherry will all top 6-7 feet. Can't find anything on one called Ultimate Opener and have never grown it but I have done all the others. But the plants don't have to be supported all the way. They just drape back over and keep growing. So the easiest thing to do would be to pick up a bundle of 6-8 foot stakes from any lumber yard and use one on each. OR invest in several 16 foot long cattle panels and some 5 foot fencing stakes to wire them to and plant along them. Otherwise, you are likely to end up with an unmanageable jungle. ;) Good luck.

There are only two patterns on the Premier yarns website using the trellis yarn. One pattern involves crocheting, and the other is neither crocheted NOR knitted. See: http://www.premieryarns.ca/product.aspx?id=6896&pid=166517 And while snooping around the Internet, I found: "Similar to Lion Brand Trellis and Bernat Matrix, City Life Ladder yarn is a glitzy ladder yarn." HTH.

Nice trellis! Thanks for the tutorial
