To build the trellis, sink poles or 4-inch wooden posts into the ground about 10 feet apart. Be sure that they are deep enough and properly anchored to support the weight of all the tomatoes when laden with fruit. The tops of the posts should be 5 or 6 feet high.
Twine -- For trellising tomatoes, you'll want to use either jute twine, baling twine or any other soft string that won't cut through the tomato's stem. Use something that's compostable, then you can just toss it into the compost along with the tomato vine at the end of the year.
We recommend a trellis that's tall enough to accommodate growing vines, but not so tall that you'd have to stretch to pick. Our trellises measure 6 feet tall, but anywhere from 4 to 6 feet will work for growing most vining plants vertically. If your vines begin to grow out of hand, pinch off the top tip of the vine.
Choose stakes that are at least 4 feet tall for the cage supports. As for the tomato plant itself, the length of stake needed depends on the variety. Around 4 feet is usually sufficient for a determinate variety, while we often stake our indeterminate tomatoes with 6 to 8 foot tall stakes.
You want to start pruning tomato plants a when they get to be about 1 -- 2 feet (30-60 cm.) tall. Any smaller than this, and the plant may not recover from the shock of being pruned. By the time your tomato plant gets to be this size, the plant will have branches coming off the main stem.
Some gardeners recommend you “pinch off” the flowers on your tomato transplants during their first weeks of growth, claiming that removing early blossoms: Directs more energy into establishing a strong root system. Results in a larger, sturdier, and potentially healthier tomato plant.
Tomatoes should ideally be grown in a raised bed that's at least 15 to 18 inches deep. Many of my clients in Houston are successfully growing tomatoes in 12-inch deep raised garden beds, but their plants tend to be a little stunted compared to plants in deeper beds.

Tomato Cage Cons
These trellises cause a bit of extra labor for you too, and pruning and thinning will become your constant task as you battle with a plant that feels a bit confined in its corset. I'm all about equipment that can multitask throughout the seasons and take up minimum space during any storage downtime.
A better choice is to stake your tomatoes. There are stakes available as long as 10 feet. They come in different materials like wood, bamboo, plastic and metal.
The maximum height of a garden fence with trellis on top is defined when: Your council treats a trellis as a fence or a garden wall. In this case, the total height of your fence and trellis should not exceed 2 metres; Your council treats a trellis as a “temporary structure”.
Theoretically, you can train your cucumber vines onto the same supports you use for your tomatoes. This mingling of plants is called diversified planting, which can help with pest prevention. The biggest concern here is airflow and sun exposure.
Planting on the inside of a trellis or arbor means your climbing plants are positioned between the trellis and the structure it's against, like a wall or fence. This approach can create a lush, green backdrop, allowing your plants to grow against a solid surface.
Give your tomato plants spacious accommodations
After I set up the trellises, I put in five tomato plants per 10-ft. trellis.
Most determinate varieties need a cage, but there are some very stocky varieties, such as Better Bush, that have a very sturdy main stems; they don't need much support, just a stake to keep them from toppling in wind and rain.
Large, thickly fleshed beefsteaks are the biggest type of tomatoes, weighing 1 pound or more. Growing quickly to at least 6 feet tall, the late-maturing tomato plant will produce a bountiful harvest in about 85 days. It needs a sturdy cage, trellis, or stake to support its fruit.
Water or heat stress
This is a common occurrence in mid-summer and is associated with high temperatures and moisture stress. Some tomato varieties, including heavily pruned determinate-type varieties, are more prone to leaf roll.
Welded wire “cattle panels” make great tomato trellises. They stand up well; clean easily; and the openings are big enough that tomatoes don't get stuck growing into them.
The problems with a spiral is that it isn't nearly tall enough to handle an indeterminate tomato and it offers no support to side stems.
Buying individual tomato cages is perhaps the lowest effort, but most expensive option for trellising your tomatoes, especially if you grow many plants each year. These cages are easy to find at your local hardware or garden store, and come in a variety of sizes and colors.
Tomatoes are vigorous growers that need lots of room for roots to spread out. Containers should be at least 5 gallons or 12 inches wide and deep, though bigger is better.
Cage Method
One of the most common methods of trellising for the home gardener is caging. Traditional tomato cages that many gardeners know are best for determinate (or bush) tomatoes, which top out at about 5 feet tall. Cages also work well when you're growing in pots.
Plant Tomatoes
Plant them at 18- to 24-inch spacing. Don't worry about letting the plants lean to one side; in a few days, they straighten up on their own.
