Trellis material and types

Substantial trellis support is needed for several crops in the garden. This includes tomatoes, peas, pole beans, cucumbers, tomatillo and pepper. There are 200 feet of 8 double row beds for tomatoes.
I really need to decide on the material. My favorite methods may be too expensive.

Spiral tomato trellis is simple and compact.

Here is a spiral trellis. They are spiral wire stakes with one end in the ground and the other supported by a wire running the length of the row. The wires require a fence post every 10 feet to prevent the plants from swaying with the wind. Suckers are pruned so that only the main vine grows producing a very compact form. Weeding and fertilizer applications and harvesting is very easy. But 200 stakes are needed and at least 42 steel fence posts. Ugh. That is $500 just for tomatoes.

Another method uses fence posts (or some rigid stake) along each row. Jute twine is then woven between plants and stakes. As plants grow another line of twine is added above the last. Often, wooden stakes are mixed with more rigid fence posts. Wood stakes are placed every 2 or 3 plants. This calls for 32 fence posts and 42 wood stakes. Hmmm.

Peppers and tomatillos will be easy. Flat fence panels supported with stakes driven into the ground will work great. Panels are 4 feet wide, have nice big holes for weeding and grooming and support plants about 1 foot off the ground.

Pepper trellis. Using wood blocks to hold up panels is a bad idea unless blocks are secured to the raised bed. A single panel could cover the entire 16′ bed.

Peas and beans remain. I am thinking of a plastic mesh folded over a tall wire supported with tall fence posts (6′ above ground +2′ below = 8′ posts). I have seen beans grow 6 feet tall. Beans will be planted on top of the peas’ dying vines. Ideally, the beans will be 1 foot tall just as the peas begin to fade from summer’s heat. A single post for two rows of peas with mesh staked down with each row and both pieces of mesh secured to one wire. (a long tee pee). I am concerned about wind load and my inexperience growing so many peas.

After the blackberries have been in the ground for 1 year they will need a trellis. Everything in its own time.
