From sweet cherry to beefsteak, tomato plants have one thing in common: the need for tomato cages. Because tomatoes are vining plants, supporting them from an early stage is critical to their ability to grow tall and strong and produce healthy, plentiful tomatoes. 

Since there are almost as many tomato growing cages on the market as there are tomato varieties, we recently put 13 top options to the test to find the best ones. Once our efforts were complete, we chose the Gardener’s Supply Company Tomato Cages as our top pick. These heavy-gauge square tomato cages are incredibly easy to set up, fold flat for storage, and are among the most durable galvanized steel cages we’ve ever used. 

But there were several other durable and user-friendly plant cages that offered excellent support for tomato plants as well. Read on to learn more about the best tomato cages you can get for your garden.

Our Top Picks

The following tomato cages made our list of recommended picks for their blend of reasonable cost, useful versatility, and lasting durability. Regardless of the size of your budget or the size of your garden, one of them should be just what you need to produce gorgeous, fruitful tomato plants this season.

Taking the top spot for best tomato cages are these folding square cages from Gardener’s Supply Company. They’re easy to set up, provide plenty of space for even the largest tomato varieties, and have an opening wide enough for harvesting and pruning tomato plants throughout the growing season. Because these sturdy steel wire cages are powder-coated in red or green, they’re not only attractive in garden beds but also stay cooler than bare metal in the sun. Their larger cage size means they also work well for a variety of other vining plants, including beans (especially bush beans), peas, cucumbers, and small squash.

In our tests, these heavy-duty tomato cages were some of the easiest to uninstall, collapse, and store. Their generous size was perfect for supporting tomato plants while allowing plenty of room for companion planting alongside basil, lettuce, or other low-growing veggies. Because of their size, however, they may not fit in containers. 

What our tester says: “I’ve gone through dozens of tomato cages in my lifetime as a gardener. Many of the thin ones buckle and bend, which makes them harder to store and reuse each year. The Gardener’s Supply Tomato Cages fold flat for easy off-season storage yet are sturdy enough to maintain their exact shape. I’m excited to have finally found a tomato cage that will actually last.”—Amber Guetebier, Product Reviews tester and writer

With 10 included wire plant cages, this set from Panacea Products is a great buy for a prolific garden. Made of galvanized steel wire, each cage measures 33 inches tall, 6 inches in diameter at the base, and 12.1 inches in diameter at the top. This narrow bottom allows them to fit easily into gardens or planters, and the large opening simplifies harvesting when your crop is ripe and ready. When you’re done supporting tomatoes for the season, each cage stacks atop another for simple storage. 

Though they’re relatively cheap tomato cages, they held up well in stormy weather and also fit other garden plants, such as lilies or sunflowers, well. However, like many non-folding tomato cages, the feet can bow and bend when repositioned, making them a little less sturdy for year-after-year use.

Available in a two-pack, these square-shaped tomato cages from MTB Supply are made of galvanized steel. They measure 46 inches tall by 12 inches wide, which means they’re big enough for large tomato varieties. When not in use, each collapsible tomato cage folds flat for easy storage. 

One thing we really liked about this pick is that you can use each galvanized tomato cage alone or connect two together to create a lattice, making them well-suited for growing peas, cucumbers, or beans. Be aware, however, that the wire doesn’t have any type of coating, which means these colored tomato cages​ may stand out in the garden and get pretty hot in the summer sun.

What our tester says: “These felt like a great investment for several reasons: They held up well to all of my stress tests and stayed in great shape after being set up and taken down several times. Best of all, I used a couple as trellis, and they worked great for sweet peas, beans, and even a clematis I’d just planted.”—Amber Guetebier, Product Reviews tester and writer

This set from K-Brands comes with three green triangular tomato cages made of coated steel and plastic, which helps camouflage them in the garden for a neat, attractive look. As an adjustable-height option, they’re perfect for use from seed through to harvest, and the included snap-on clips make it easy to secure and support a tomato plant as it grows.

While the cages do require a bit of time-consuming assembly, no tools are necessary. You can set them up to be a full 68 inches high, making them great for larger tomato varieties. The green coating prevents the steel core from overheating in the sun and resists rust in the rain, but the plastic connectors you use to adjust the height may shorten this pick’s overall lifespan.

This Vego trellis offers one of the sleekest designs we’ve seen for a tomato plant trellis and cage. Assembled from aluminum tubes, it has more visual heft than a thin wire frame, but the rounded edges and domed top feel very modern. The aluminum construction is also durable enough not to bend and is easy to clean. 

While Vego doesn’t sell the cage on its own, we’ve spotted the planter sold separately for about $30 less, making the cage more expensive than other options on this list (especially since they’re all sold as multi-packs). Still, the full kit is one of our favorite self-watering planters, as its reservoir keeps tall plants well-watered by wicking water from the bottom and its air pockets encourage circulation for improved root health. Thanks to this thoughtful design, our tomatoes survived two separate heat waves during testing without daily watering. The only hiccup we ever ran into was that the connectors sometimes pop free if you twist the cage while moving the planter. 

What our tester says: “The ability to build the Vego to three different heights is a double-edged sword. It’s great to adjust it to the stage of current tomato growth or fit it to another type of vining plant, but it also takes a bit of care to make sure its rods are snugly set in their connectors.”—Kathleen Corlett, Editor in Chief and product tester

This tomato plant cage set from Mimeela includes four circular plant cages, four self-watering spikes, and 20 plant support clips. Each cage measures 24 inches high and has a 7.1-inch bottom diameter that’s ideally sized for small pots and grow bags, and its steel frames are plastic-coated for increased durability and rust resistance.  

There was a lot to like about these tomato cages in testing. The stakes have sharp caps at the bottom for easy insertion as well as a rounded one at the top to prevent rainwater from getting inside. The height rungs are adjustable, so you can modify support as your plants grow, and the included spikes turn this set into a self-watering one by providing consistent moisture. We did cycle through a few styles of plastic bottles before we found something that fit the spikes (2-liter soda bottles work), but for the convenience the spikes provide, that bit of initial effort proved worth it.

How We Chose the Best Tomato Cages 

After choosing 13 popular tomato cages to test, we began our evaluation by noting how easy or difficult each one’s assembly process was. We then set them up in our garden for a minimum of 4 weeks, evaluating them for durability in a variety of weather conditions—including heavy storms with high winds and long stretches of sunlight sure to break down low-quality materials. We dropped them from a height of 8 feet onto both grass and concrete and repeated the assembly and disassembly process several times to see if any options would end up bent. 

The six models that made our list of the best tomato plant cages are primarily made with durable galvanized steel and coated with either plastic or PVC for weather resistance. We found round, triangle, and square shapes we liked, and selected cages that come in various sizes to accommodate everything from seedlings to fully grown plants (with some reaching heights of nearly 7 feet tall). Virtually all the tomato cages we included are easy to assemble with snap-on clips or connecting pieces, and some even come completely preassembled. 

What to Consider When Choosing Tomato Cages 

Tomato cages help keep tomatoes upright and may even increase yield. To choose the best tomato wire cage from the hundreds available, keep the following considerations in mind.

Material

While plastic and wooden tomato cages exist, most are constructed from some type of metal. These wire cages for tomatoes might be made from uncoated metal, plastic- or powder-coated metal, or galvanized steel. Uncoated metal is durable but may rust, while metal that’s coated with plastic or powder provides better water and heat resistance. Uncoated metal can get hot enough to burn you as you reach for a ripe tomato, while coated metals won’t heat up nearly as much. Galvanized steel is zinc-coated for weather protection without the use of plastic.  

Size

Tomato cages range in size, with smaller ones measuring as little as 15 inches in height and larger ones reaching up to 72 inches. 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 planter cages offer height adjustment, which makes them suitable for various types of tomatoes.

Shape

Tomato cages come in three main shapes: curved-link stakes, triangular, and ring style: 

• Curved-link stakes, often rectangular or square-shaped, often provide the best support for strong plants with heavy tomatoes. They generally fold up easily for simple storage when the season ends.
• Triangular cages have bars that are relatively close together, making them ideal for smaller varieties of tomatoes. 
• Ring-style cages have a circular shape that provides plenty of room for tomato plants to grow, which can result in a higher yield, especially when paired with the right tomato fertilizer.

Assembly 

Learning how to use tomato cages is fairly straightforward, especially with preassembled ones. However, even those that have stabilizing poles and connecting pieces you need to attach rarely require tools or even two sets of hands. Generally speaking, large cages are more likely to need a bit of assembly than small ones. 

Tips for Using Tomato Cages 

Just like the right soil for tomatoes, the best tomato cages can help plants stay healthier and produce more tomatoes—but only if used correctly. To provide the maximum benefit, they must be properly placed and secured.

Follow these three tips for properly using tomato cages:

• Use only one tomato cage per tomato plant.
• Bury the cage legs several inches in the soil to ensure it’s secure.
• As a tomato plant grows, use ties or clips to guide and secure the vines.
• Monitor for pests and treat with an insecticide designed for vegetable gardens as necessary.

FAQs 

If you’re just learning how to grow tomatoes, the following answers to some commonly asked questions about tomato cages can help.

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 it. For smaller varieties, cages of 15 inches high and 10 inches wide work well. Larger varieties will require cages that are at least 38 inches high and 14 inches wide.

Q. How deep should a tomato cage be?

The tomato cage legs should be inserted at least 6 inches into the soil to prevent tipping.

Q. When should I cage my tomato plants?

Since tomato cages need to be inserted into the soil, cage your tomato plants during the planting process (or when you move them outdoors) so that you don’t disrupt their root system during the growing process. 

Q. Are square tomato cages better?

The primary advantage of square tomato cages is their ability to fold flat for storage. Square cages may also accommodate larger, heavier tomato varieties better than smaller cone-shaped options.

Q. What happens if you don’t use tomato cages?

Since many tomatoes are indeterminate (vining) plants rather than determinate (bushy, compact), they need support to prevent them from spreading across the ground, as this can lead to tomato plant problems like being eaten by insects, worms, or animals, or breaking under the weight of ripening fruit. Even varieties that don’t vine benefit from cages to keep fruit off the soil and improve air circulation.

Q. How many tomato plants can you put in a tomato cage?

When growing tomatoes, it’s best to put just one plant in each cage so it has plenty of room to grow, gets good airflow, and is easy to harvest.

Q. Can you put tomato cages upside down?

Yes, you can put tomato cages upside down to support bushy plants you didn’t initially cage, or to add extra height for especially tall ones.
