What to Consider When Choosing the Best Tomato Cages
Tomato cages help keep tomatoes upright and may even increase the yield of the plants. But how do you choose the best tomato cage? Keep the following considerations in mind when shopping: the construction material, the size and shape of the cage, and assembly options.
Most tomato cages are made of metal with some slight variations. They may come in uncoated metal, coated metal, or galvanized steel. While metal can provide a durable and secure tomato cage, uncoated metal may rust. Coated metal, whether coated plastic or powder, provides better weather resistance.
Another benefit of coated metal is temperature. Uncoated metal can get fiery hot in the sun. If you touch it as you reach for a ripe tomato, it may really burn. Coated metals won’t heat up so much. Consider the planned location of the cages and whether rust resistance matters before you choose a metal.
Tomato cages range in size, with smaller ones measuring up to 15 inches high and larger ones reaching 72 inches high. The right size for you will depend on the size of your garden and what type of tomato plants you plan to grow.
For smaller varieties of tomatoes, such as Tiny Tim and New Big Dwarf, smaller tomato cages should do the trick. Larger plants, such as Beefsteak and Big Boy, will require larger tomato cages. Some tomato cages offer height adjustment, which makes them suitable for various kinds of tomatoes.
Tomato cages come in three main shapes: curved-link stakes, triangular, and ring style:
- Curved-link stakes, often rectangular, may provide more stability than ring-style cages. They also provide better support for heavier tomatoes and stronger plants. These cages fold up easily for simple storage.
- Triangular cages allow a tomato plant more support for optimal growth because the bars are closer together, which makes them ideal for smaller varieties of tomatoes.
- Ring-style cages with their circular shape provide ample room for tomato plants to grow, which can result in a higher yield, especially when paired with the right tomato fertilizer.
Some tomato cages come preassembled; others require assembly with stabilizing poles and connecting pieces. Few tomato cages require tools or assistance to assemble. Generally, larger tomato cages require assembly, while smaller ones may come preassembled or require fewer assembly steps.
For those concerned about assembling a tomato cage, check the manufacturer’s assembly instructions prior to purchase.

An included 328 feet of garden twist tie helps secure the plants to their posts. Nine included clips keep vines in place. The cages’ green color blends in with tomato plants and the overall look of the garden.
For those growing smaller varieties of tomatoes, these ring-style tomato cages from LEOBRO measure just 15.6 inches high and 9.4 inches wide, yet they offer plenty of support. Available in a pack of four, the cages can stand alone in a half-circle or combine to create a full circle around a plant.

With 10 included plant cages, this set from Panacea Products belongs in a fruitful garden. Made of galvanized wire, the cages measure 33 inches tall, 6 inches in diameter at the base, and 12 inches in diameter at the top.
The three-rung tapered design provides a sturdy base for small tomatoes and other climbing fruits and vegetables. A smaller bottom diameter means they can fit easily in a garden or an indoor planter, while the large top opening makes it easy to harvest tomatoes when they’re ripe and ready. When not in use, the cages stack for simple storage.
Available in a two-pack, these square-shaped tomato cages from MTB Supply come in rust-resistant galvanized steel. But buyer beware: the wires don’t have a plastic coating, which means their color may stand out in the garden, and they will get pretty hot in the sun.

Tips for Using Tomato Cages
The best tomato cages can certainly help plants stay healthier and produce more tomatoes, but only if used correctly. Tomato cages need to be properly placed and secured around the plant to maximize the benefits. Some cages also include accessories, like plastic ties or clips, to help secure the plant as it grows.
Follow these three tips for properly using tomato cages:
- Use only one tomato cage per tomato plant.
- Submerge the legs of the tomato cage at least several inches into the soil to ensure it is secure.
- As a tomato plant grows, use ties or clips to guide and secure the vines through the cage.
FAQs About Tomato Cages
If you’re hoping to grow tomatoes, here are the answers to some commonly asked questions about tomato cages.
Q. What is the purpose of tomato cages?
Tomato cages help plants grow vertically to keep tomatoes off the ground, which can result in stronger, healthier plants and—as a result—more tomatoes.
Q. How big should a tomato cage be?
The size of the best tomato cage for you depends on the size of the tomato plants that will grow inside them. For smaller varieties, cages of 15 inches high and 10 inches wide work well. Larger varieties will need cages that reach a minimum of 38 inches high and 14 inches wide.
Q. How deep should a tomato cage be?
The tomato cage legs should insert at least 6 inches into the soil to prevent tipping.
Q. When should I cage my tomato plants?
Since tomato cages are submerged into the soil, cage tomato plants during the planting process (or when you move them outdoors) so you don’t disrupt the plant’s root system later in the growing process.
A tomato cage is a worthy investment for any home gardener. By encouraging upward growth and keeping tomatoes off the ground, a tomato cage will yield healthier, juicier, and more plentiful tomatoes. With the above recommendations in mind, you can choose a suitable tomato cage for a more bountiful harvest.
