Vegetables That Thrive on Trellises: A Vertical Gardening Guide

Trellises are not just for climbing roses and clematis; they're also excellent for growing a variety of vegetables. By providing vertical support, trellises help maximize space, improve air circulation, and make harvesting easier. Let's explore the best vegetables to grow on trellises and how to cultivate them effectively.

Trellising vegetables offers numerous benefits, including increased yield, improved plant health, and easier pest management. It's a great way to grow both climbing and vining vegetables, as well as some that can be trained to grow vertically. So, let's dive into the world of trellised vegetables.

Climbing and Vining Vegetables

Climbing and vining vegetables are those that naturally grow upwards using tendrils, runners, or other means of attachment. Trellises are ideal for these plants, providing them with the support they need to grow tall and produce abundantly.

Here are some popular climbing and vining vegetables that thrive on trellises:

Cucumbers

Cucumbers are prolific climbers, with some varieties producing fruit throughout the growing season. They grow best on sturdy trellises made of wire mesh, netting, or heavy-duty plastic. To encourage vertical growth, plant seeds or transplants at the base of the trellis and gently guide the tendrils as they grow.

Popular trellising cucumber varieties include 'Boston Pickling', 'Burpless Tasty Green', and 'Homemade Pickles'. Keep in mind that bush cucumber varieties, such as 'Spacemaster' and 'Salad Bush', do not require trellising.

Peas

Peas are cool-season climbers that produce edible pods. They grow well on trellises made of netting, chicken wire, or even bamboo stakes. Plant peas in early spring or late fall, depending on your climate, and provide them with consistent moisture for optimal growth.

Some popular trellising pea varieties include 'Sugar Snap', 'Snowbird', and 'Little Marvel'. For a continuous harvest, succession plant peas every two weeks until temperatures consistently reach the 70s Fahrenheit.

Vegetables Trained to Grow Vertically

Some vegetables are not naturally climbers but can be trained to grow vertically on trellises. With a little extra effort, you can maximize space and improve plant health by trellising these vegetables.

Here are two vegetables that can be trained to grow vertically:

Indeterminate Tomatoes

Indeterminate tomato varieties continue to grow and produce fruit throughout the growing season. While they don't naturally climb, they can be trained to grow on trellises made of stakes, cages, or even strings. As the plants grow, gently tie the stems to the trellis and prune suckers to encourage vertical growth.

Popular indeterminate tomato varieties for trellising include 'Brandywine', 'Cherokee Purple', and 'Green Zebra'. Keep in mind that determinate tomato varieties, such as 'Roma' and 'Patio', are not suitable for trellising as they grow to a certain size and then stop.

Zucchini

Zucchini plants have large, heavy leaves and produce abundant fruit. While they don't naturally climb, they can be trained to grow vertically on trellises made of wire mesh, netting, or heavy-duty plastic. As the plants grow, gently tie the stems to the trellis and remove any side shoots to encourage vertical growth.

Popular trellising zucchini varieties include 'Black Beauty', 'Golden Zucchini', and 'Eight Ball'. Keep in mind that bush zucchini varieties, such as 'Bush Baby' and 'Round Zucchini', do not require trellising.

Incorporating trellises into your vegetable garden can significantly improve plant health, increase yield, and make harvesting easier. By providing vertical support, you'll create a more efficient and productive garden space. So, start planning your trellised vegetable garden today and enjoy the benefits of growing up!
