10 Plants to Grow in Tomato Cages That Aren’t Tomatoes: A Guide to Maximizing Your Garden Space

Tomato cages are typically associated with growing tomatoes, but did you know that they can be used for a variety of other plants too? These sturdy structures can provide vertical support to many types of climbing plants, saving you valuable garden space and enhancing plant health by keeping their fruits off the ground. In this article, we’ll explore 10 plants that thrive in tomato cages, helping you make the most of your garden space and resources.

Introduction: The Versatility of Tomato Cages

Tomato cages are a staple in vegetable gardens, designed to support the vigorous growth of tomato vines. However, these cages are not exclusive to tomatoes. With their sturdy, open design, tomato cages can be used to support a wide range of plants that benefit from vertical growth. Growing plants vertically has numerous benefits, including reducing the risk of pests, improving air circulation, and making harvesting easier. By using tomato cages for other crops, you can maximize your garden space and increase your yield. Here are 10 excellent plants that are perfect for growing in tomato cages.


1. Cucumbers: The Perfect Vine for Vertical Gardening

Cucumbers are among the most popular vegetables for vertical gardening. Their sprawling vines can quickly take over garden beds, but using a tomato cage allows them to grow upright, saving space while producing more fruit. With a sturdy tomato cage, your cucumbers will have the support they need to grow tall, rather than spreading out on the ground.

How to Grow:

  • Plant cucumber seeds or seedlings at the base of the tomato cage.
  • As the vines grow, gently guide them up the cage to help them climb.
  • Ensure the cage is tall enough to accommodate the full length of the cucumber vines.
  • Harvest cucumbers when they reach the desired size, typically 6-8 inches long.

2. Peas: A Climbing Classic

Peas are another ideal plant for tomato cages. As a climbing plant, peas naturally grow upwards, so they’ll thrive when given a structure like a tomato cage. Whether you’re growing snap peas or snow peas, they’ll happily climb the cage and produce an abundant harvest.

How to Grow:

  • Sow pea seeds at the base of the tomato cage, spacing them around 2 inches apart.
  • As the plants grow, encourage them to climb the cage by gently tying them with twine or string.
  • Water regularly and provide a trellis-like environment by ensuring the cage is high enough for the peas to fully grow.
  • Harvest peas when the pods are plump but still tender.

3. Beans: Maximize Your Vertical Space

Pole beans are a great choice for tomato cages. Unlike bush beans, which grow horizontally, pole beans naturally climb and twirl their way up structures. With their fast-growing vines, beans will make excellent use of the vertical space provided by tomato cages.

How to Grow:

  • Plant bean seeds around the base of the cage, spacing them about 2-4 inches apart.
  • As the beans grow, they will naturally climb the cage, so make sure the structure is tall and sturdy enough to support them.
  • Beans thrive in warm weather, so plant them after the last frost.
  • Harvest the beans once the pods are full and before they start to dry.

4. Squash: Compact and Space-Efficient

While many people grow squash on the ground, smaller varieties like summer squash can thrive when grown vertically in a tomato cage. This method reduces the chance of pests and rot, as the fruit is elevated off the ground.

How to Grow:

  • Plant squash seedlings or seeds near the base of the tomato cage.
  • Guide the vines upwards as they grow, securing them with soft ties.
  • Make sure the cage is wide enough to accommodate the spreading vines.
  • Harvest when the fruit reaches a desirable size, usually before the skin hardens.

5. Eggplant: Support for Tall, Delicate Stems

Eggplant plants can grow tall, making them prone to bending or breaking under the weight of their fruit. Tomato cages provide excellent support for eggplants, keeping the plant upright and allowing it to bear fruit without toppling over.

How to Grow:

  • Plant eggplant seedlings at the base of the cage, ensuring they have room to grow.
  • As the plant grows, use the cage to support the stems and prevent them from flopping over.
  • Ensure the cage is tall enough to provide adequate support as the plant matures.
  • Harvest when the fruit reaches a shiny, deep color and is firm to the touch.

6. Luffa (Loofah): An Uncommon Vertical Plant

Luffa, or loofah, is an exotic plant that can be grown on a tomato cage. As a vining plant, loofah can quickly climb up structures, making it an excellent choice for vertical gardening. With its large, sprawling vines, it can use the support of a tomato cage to grow its long, fibrous fruit.

How to Grow:

  • Plant luffa seeds or seedlings near the base of the tomato cage.
  • Guide the vines up the cage as they grow, securing them if necessary.
  • Be patient – luffa can take a while to mature, often requiring several months of warm weather.
  • Harvest when the fruits turn brown and dry, indicating they are ready to be turned into loofah sponges.

7. Morning Glory: A Beautiful Climbing Flower

If you’re looking to add beauty to your garden while maximizing space, morning glory is an excellent option. These vibrant climbing flowers are perfect for growing on a tomato cage, where they will quickly spiral upwards and produce colorful blooms.

How to Grow:

  • Plant morning glory seeds at the base of the cage.
  • The vines will naturally climb the cage, producing trumpet-shaped flowers in various colors.
  • Morning glories thrive in full sun, so place the cage in a sunny spot.
  • Enjoy the blooms in summer and fall, and let the vines cover the entire structure.

8. Melons: Save Space with Vertical Gardening

Smaller melon varieties, like cantaloupes, can be trained to grow on a tomato cage. This method helps to keep the fruits off the ground and minimizes the risk of rot. Melons that grow vertically also take up less space, allowing you to grow more in a small garden.

How to Grow:

  • Plant melon seeds or seedlings around the base of the cage.
  • As the plant grows, guide the vines to climb the cage.
  • Ensure that the cage is sturdy enough to support the weight of the growing melons.
  • Harvest when the melons are fully ripe and have a sweet aroma.

9. Peppers: Support for Tall Varieties

Peppers, especially tall varieties like bell peppers, can benefit from the support of a tomato cage. The cage helps prevent the branches from breaking under the weight of the fruit, keeping the plant upright and ensuring a healthy harvest.

How to Grow:

  • Plant pepper seedlings at the base of the cage.
  • As the plant grows, use the cage to support the stems and branches.
  • Make sure the cage is tall enough to support the height of the pepper plant.
  • Harvest when the peppers are fully colored and firm to the touch.

10. Zucchini: Vertical Gardening for Space-Saving

Zucchini is another vegetable that can be grown vertically in a tomato cage. The cage helps keep the sprawling vines contained, and it elevates the fruit, reducing contact with soil and pests.

How to Grow:

  • Plant zucchini seeds or seedlings at the base of the cage.
  • Train the vines to climb the cage as they grow, ensuring they stay upright.
  • Make sure the cage is large enough to accommodate the vines as they spread.
  • Harvest when the zucchini is firm and the skin is still tender.

Conclusion: Embrace Vertical Gardening

Tomato cages are versatile gardening tools that can support many different types of plants. By using them for other crops besides tomatoes, you can make the most of your garden space and encourage healthier, more productive plants. Whether you’re growing cucumbers, peas, or flowers, the benefits of vertical gardening are undeniable. Not only does it save space, but it also helps reduce the risk of disease, improves airflow, and makes harvesting easier.
