Trellising and Training Tomatoes
by Shepherd Ogden
In my travels to gardens and farms around the world, I've seen a variety of inventive ways to trellis tomato plants. Some of the trellises are particularly attractive, others are surprisingly strong, and still others are rather elaborate.
Choose a system suited to the number of plants you're growing, their type, and the prevailing winds in your area. Trellises suitable only for small, determinate-type plants are noted. Otherwise, assume the trellis is for indeterminates.
Here are the ten basic ways you can train tomato plants.

Here are the ten basic ways you can train tomato plants.
Compost Cages
An ingenious American trellising method. Make a 4-foot-diameter cage (minimum) from fencing or concrete reinforcing wire. Build a compost pile inside it. The following season, plant tomatoes around the perimeter and train them to grow up the outside. Rain falling on the compost will feed the plants.
- Relatively inexpensive
- Low-maintenance
- Good for determinate varieties
- Requires planning a season ahead
Single Stake
The most common method in the United States. Pound a solid stake a foot or two into the ground, and tie a single vine to it as it grows. Six-foot 1- x 1-inch stakes are usually set 2 to 3 feet apart, 2 feet deep, in rows 3 to 4 feet apart.
- Simple to construct and maintain; inexpensive
- Not wind-resistant
- Heavy pruning usually needed to keep plants attached to stakes
Bar-and-Twine Trellis
A home-scale variation of a widely used European trellis. Sink 8-foot-tall 2 x 2 rot-resistant posts 18 inches in the ground, 5 feet apart, and join them at the top with electrical conduit flattened and drilled at the ends. Tie strings to the base of each plant with a nonslip knot, then loop over the top bar. Braid stems with the strings as the plants grow.
- Uses space efficiently
- Relatively inexpensive
- Provides good air circulation
- Wind-resistant if parallel to prevailing winds
Dutch Spiral
This system is a high-tech single-stake method. Set the metal post 1 foot into the ground; as the pruned, single-stem tomato plant grows, it intertwines itself with the stake.
- Simple to set up and maintain
- Not wind-resistant
- Relatively expensive
Tall Cage of Concrete Reinforcing Wire
Almost as popular among American gardeners as the single-stake method, these cages are taller, sturdier versions of the basic tomato cage. Make one from 4-foot-wide concrete reinforcing wire, available at most building-supply stores. Set a stake just inside the cage and fasten the wire to it.
- Good for determinate varieties
- Not wind-resistant
Long Row
For this English-style trellis, set 8-foot-tall 4 x 4s 2 feet into the ground at the ends of a 20- to 50-foot row. Run a 9-gauge wire from anchors beyond each end over the top and tighten with a turnbuckle. Run twine from the plant base to the wire or tie bamboo stakes to the wire every 2 feet, and tie the stems to grow up the twine or stakes.
- Provides good air circulation
- Efficient for large-scale growers
- Wind-resistant if parallel to prevailing winds
