What to Consider When Choosing the Best Tomato Cages
Tomato cages help keep tomatoes upright and can even aid in increasing the yield of the plants. But how to choose the best tomato cages? Keep the following considerations in mind when shopping: the material with which the tomato cage is made, its size and shape, and the assembly options.
Most tomato cages are made of metal with some slight variations. Some are constructed with uncoated metal, some with coated metal, and others with galvanized steel.
While metal can provide a durable and secure tomato cage, it may be prone to rust if the metal is uncoated. Coated metal, whether with plastic or powder, can provide better weather resistance.
Another benefit to choosing coated metal is temperature. If an uncoated metal cage has been sitting in the hot summer sun, accidentally touching that metal while reaching for a ripe tomato can pose a hazard. Consider the location of the cages for sun exposure, plus their weather resistance, when considering which material to choose.
Tomato cages range in size, with smaller ones measuring up to 15 inches high and larger ones reaching 72 inches high. Choosing the right size will depend on what type of tomato plants will be growing inside them. For smaller varieties of tomatoes, such as Tiny Tim and New Big Dwarf, smaller tomato cages should do the trick.
For larger tomato plants, such as Beefsteak and Big Boy, larger tomato cages would naturally be more appropriate. Some tomato cages also offer adjustable heights, making them a more versatile solution for various kinds of tomatoes. Also keep in mind the size of the garden space when shopping for tomato cages.
Tomato cages are available in three primary shapes: curved-link stakes, triangular, and ring style:
- Curved-link stakes are often rectangular and can provide more stability than ring-style cages as well as provide better support for heavier tomatoes and stronger plants. They can also fold up easily for simple storage when the gardening season ends.
- Triangular cages allow a tomato plant more support for optimal growth because the bars are closer together, making them ideal for smaller varieties of tomatoes.
- Ring-style cages with a circular shape provide ample room for tomato plants to grow, which can result in a higher yield of plants, especially when paired with the right tomato fertilizer.
Some tomato cages are preassembled; others require putting together stabilizing poles and connecting pieces. Most tomato cages do not require tools or assistance to assemble. Generally, larger tomato cages will require assembly, while smaller ones may be preassembled or at least require fewer assembly steps.
For those concerned about assembling a tomato cage or who prefer the tomato cage to be as easy to put together as possible, check the manufacturer’s assembly instructions prior to purchase.
Our Top Picks
The following tomato cages made the list of top picks due to their cost, versatility, and durability. Read on for some of the best tomato cages on the market in a variety of categories to help produce gorgeous, healthy, and fruitful plants this season.
This three-pack from K-Brands features triangular tomato cages made of plastic-coated steel, which will both protect the metal from rusting and prevent it from becoming too hot in warm weather. They each extend up to 72 inches high, so they’re appropriate for larger varieties of tomatoes. The snap-on clips make it easy to thread tomato vines through the cage and secure them as plants grow.
The size of each tomato cage is also adjustable, meaning even tomatoes that start small can grow into them. The green color helps these tomato cages blend in well with the plants, which can create a neater and more attractive appearance for gardens. While the cages do require assembly, no tools are necessary.
This three-pack from GROWNEER features triangular tomato cages made of plastic-coated steel. After an easy, no-tools-required assembly, each cage extends to 51 inches tall and 13 inches wide. Each cage adjusts to accommodate smaller sizes of tomatoes or tomato plants as they grow and can also be easily built around plants.
Also included in this three-pack is 328 feet of garden twist tie to better secure tomato plants to their posts, in addition to nine clips to secure vines. The green color of the cages blends in with plants and helps maintain a simplified aesthetic in a garden.
For those growing smaller varieties of tomatoes, these ring-style tomato cages from LEOBRO come in a compact size at just 15.6 inches high and 9.4 inches wide, yet they offer plenty of support for the plants. Available in a pack of four, the cages can be configured to stand alone in a half-circle or combined to create a full circle around a plant.
Made with metal and covered in a green plastic coating, these tomato cages are discreet, durable, and easy to use. Their two-piece construction means they can easily be placed around plants for support without harming them. They also require virtually no assembly beyond connecting the two halves to construct the entire circle.
Available in a two-pack, these square-shaped tomato cages from MTB Supply are made of galvanized steel to prevent rusting and corrosion. However, the steel is not plastic coated, meaning the steel won’t blend in as well with the plants in the garden and can also potentially pose a burn hazard when handling it in hot temperatures.
Each cage can be used on its own; the two can also be connected for use as a lattice in the garden. Measuring 46 inches tall by 12 inches wide, these tomato cages can accommodate large tomato plants with ease. Additionally, for larger tomato varieties, the square shape offers a sturdy, durable solution. The cages fold flat when not in use, making them easy to store when the growing season is over.
Tips on 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 top three tips for properly using tomato cages:
- Only use one tomato cage per tomato plant.
- Make sure the legs of the tomato cage are submerged at least several inches in 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
For newcomers to tomato cages, here are the answers to some commonly asked questions that will help you to understand their purpose, how large they should be, and when to start using them.
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 right tomato cage to choose depends on how big the tomato plants are that will grow inside them. Smaller varieties can use cages that are around 15 inches high and 10 inches wide, while larger varieties will need cages that are a minimum of 38 inches high and 14 inches wide.
Q. When should I cage my tomato plants?
Since tomato cages are submerged into the soil, cage tomato plants as soon as they are planted (or whenever they are moved outdoors) so the plant’s root system isn’t disrupted by installing cages later in the growing process.
