Growing Nasturtium in Vegetable Garden Spaces

Sharing is caring!

Successfully growing nasturtium in vegetable garden beds and beyond brought us so much joy! The lovely pops of color in coral and cherry rose are delightful to see alongside our tomatoes and in our cucumber bed.

Last year I couldn’t get the nasturtium seedlings to take off in our container garden. This year, I’m pulling seeds to save for next year left and right. I am even sending some to my brother so he can start a small garden!

Growing nasturtium in a vegetable garden is a great way to maximize your space and enjoy companion planting.

Once they get established, nasturtium flowers need very little attention to thrive.

Let’s dig into learning more about this cool flower and the benefits of growing nasturtium in the veggie garden!

What do nasturtiums look like?

Nasturtiums look like a tropical plant boasting attractive flowers with five petals. The bright green leaves are rounded and broad with veins leading to a central stem, reminiscent of lily pads. Nasturtiums popularly come in shades of red, yellow, orange, pink, coral, burgundy, and cream.

How do nasturtiums grow?

Nasturtiums grow one leaf at a time. The nasturtium seedlings start with tiny leaves that are miniature versions of their actual leaves. As they grow larger, nasturtiums may climb, cascade, or grow in a bush form. They put out many flowers at once, and those flowers eventually form and drop seeds that you can easily find on the ground in your garden.

How do you use nasturtium as a trap crop?

Plan to plant nasturtium as a trap crop several weeks in advance of the crops you’re trying to protect. This allows the nasturtium to grow larger so that it is more attractive to pests than their normal targeted plants. According to NC State Extension, aphids are attracted to the nasturtium’s flowers and foliage. Pat West, master gardener UCCE, of the University of California UC Master Gardeners of Inyo & Mono Counties, advises that systemic strategies can help against squash bugs, such as companion planting with nasturtium, radish and other crops.

In my own experience, our nasturtiums attracted squash bugs. I am hopeful this took them away from our cucurbits like zucchini and summer squash.
