Are Nasturtiums Good for Vegetable Gardens

Nasturtiums are good for vegetable gardens, and in this article, we will explore the many ways these beautiful flowers can enhance your gardening experience. From pest control to soil enrichment, and even as a companion plant, nasturtiums offer a range of benefits that can positively impact the health and growth of your vegetables.

Nasturtiums, scientifically known as Tropaeolum majus, are not only visually appealing but also serve multiple purposes in the garden. These versatile plants are celebrated for their ability to attract beneficial insects while repelling harmful pests – making them an important ally in maintaining a balanced ecosystem within your vegetable garden.

In addition to their role in pest control, nasturtiums also have the capability to enrich the soil with essential nutrients. Their leaves and flowers act as a natural fertilizer, promoting healthy growth for surrounding plants. By understanding the benefits of nasturtiums, you can make informed decisions about incorporating them into your vegetable garden for improved overall yield and plant health.

What Are Nasturtiums

Nasturtiums, scientifically known as Tropaeolum majus, are colorful and versatile plants that are often grown in vegetable gardens for both their aesthetic appeal and practical benefits. These annual plants are native to South and Central America, and are well-loved for their vibrant flowers, which come in shades of yellow, orange, and red. Nasturtiums also produce edible leaves and flowers which have a peppery flavor, making them a popular choice for culinary use.


Nasturtiums are known for their round leaves and trumpet-shaped flowers that bloom throughout the summer months. They are easy to grow from seeds and can thrive in various soil types and weather conditions. These hardy plants can also be trailing or climbing, making them suitable for hanging baskets or trellises. Additionally, nasturtiums attract pollinators such as bees and butterflies, further benefiting the overall health of your vegetable garden.


Aside from their ornamental value, nasturtiums offer numerous benefits to vegetable gardens. They act as a natural pest control by repelling certain harmful insects such as aphids, whiteflies, and squash bugs. The pungent scent emitted by the plant serves as a deterrent for these pests, protecting your vegetables from potential infestations.

Furthermore, nasturtiums are nitrogen-fixing plants, meaning they have the ability to add nutrients to the soil by converting atmospheric nitrogen into a form that is accessible to other plants. This makes them an excellent natural fertilizer for your vegetable garden.

The Role of Nasturtiums in Pest Control

Nasturtiums are not only a beautiful addition to any vegetable garden, but they also serve a practical purpose in pest control. Here are some of the ways these flowers can protect your vegetables:

  • Aphid deterrent: Nasturtiums emit a scent that repels aphids, which are common pests in many vegetable gardens. By planting nasturtiums near susceptible vegetables such as beans or brassicas, you can help prevent aphid infestations.
  • Trap crop: Nasturtiums can act as a trap crop for certain insect pests. Some insects are more attracted to the bright colors and succulent leaves of nasturtiums, which can divert them away from your other vegetables.
  • Repellent properties: The pungent smell of nasturtium leaves and flowers can also deter other pests such as cucumber beetles and whiteflies. Planting nasturtiums throughout your vegetable garden can create a natural barrier against these unwelcome visitors.

In addition to their pest-repelling abilities, nasturtiums also have a role in attracting beneficial insects like ladybugs and predatory wasps, which feed on common garden pests. By creating a more balanced ecosystem in your vegetable garden, nasturtiums can contribute to overall pest control in a natural and sustainable way.

Adding Nutrients to the Soil

Nasturtiums are not only beautiful and versatile plants, but they also provide numerous benefits to vegetable gardens. One of the key advantages of growing nasturtiums in your garden is their ability to add nutrients to the soil as a natural fertilizer. This section will explore the ways in which these vibrant flowers enrich the soil, promoting healthy and productive vegetable growth.

Rich in Nutrients

Nasturtiums are known for their ability to draw up nutrients from deep within the soil, making them available to other plants in the vicinity. These flowers are particularly adept at accumulating phosphorus, which is essential for strong root development and overall plant health. In addition, nasturtiums also contain high levels of potassium and trace minerals, further contributing to the enrichment of the surrounding soil.

Improving Soil Structure

As nasturtiums grow, they send out long, trailing roots that help to aerate and loosen compacted soil. This improves drainage and allows air and water to penetrate more effectively, creating an environment that is conducive to healthy root growth for other vegetables in the garden. The organic matter produced by decaying nasturtium leaves further enhances soil structure by increasing its ability to retain moisture and nutrients.

Suppressing Weeds

The dense foliage of nasturtium plants effectively shades the ground beneath them, inhibiting the growth of weeds. By preventing competing plants from taking root and thriving in your vegetable garden, nasturtiums give your crops a better chance at accessing all available nutrients without having to compete with unwanted plants for resources. This natural weed suppression reduces the need for potentially harmful chemical herbicides while keeping your garden beds clear for optimal vegetable growth.

Companion Planting With Nasturtiums

Nasturtiums are not only beautiful and versatile plants but also serve a purpose in vegetable gardens. When it comes to companion planting, finding the perfect vegetables to pair with these flowers can greatly benefit your garden. Here are some vegetables that work well when planted alongside nasturtiums:

  • Tomatoes: Nasturtiums help repel pests that commonly affect tomatoes, such as aphids and whiteflies. Placing them near tomato plants can help protect them from these destructive insects.
  • Cucumbers: Nasturtiums act as a natural deterrent for cucumber beetles, which can cause damage to cucumber plants. Planting nasturtiums around cucumbers can help keep these pests at bay.
  • Radishes: Nasturtiums can attract beneficial insects like bees and hoverflies, which play a crucial role in pollinating radish flowers. This can lead to better yields for your radish crop.

In addition to their pest-repelling properties, nasturtiums also provide ground cover and shade for the soil, which can benefit neighboring vegetable plants. They have shallow root systems that do not compete heavily with other plants for nutrients and water, making them ideal companions in a crowded vegetable garden.

When considering companion planting with nasturtiums, it’s important to avoid pairing them with members of the Brassica family (such as broccoli, cabbage, and kale) as they may inhibit the growth of these plants. With careful planning and consideration of the needs of different vegetables, incorporating nasturtiums into your garden can lead to a more balanced and diverse ecosystem that supports healthy plant growth.

Growing and Caring for Nasturtiums in Your Vegetable Garden

Nasturtiums are not only a beautiful addition to your vegetable garden, but they also serve several vital functions that can contribute to the health and success of your garden. Proper growing and caring techniques for nasturtiums can greatly improve their ability to serve as a natural pesticide, fertilizer, and companion plant.

When planting nasturtiums in your vegetable garden, it’s essential to choose a location that receives full sunlight. These plants thrive in well-draining soil and don’t require very fertile ground. In fact, too much nitrogen can lead to excessive foliage growth and less prolific flowering. Additionally, nasturtium seeds can be planted directly into the soil once there is no longer any risk of frost.

In terms of care, nasturtiums are relatively low maintenance. They require regular watering, but overwatering should be avoided as it can lead to issues such as rot. Deadheading – or removing spent blooms – encourages continued flower production. Overall, providing proper growing conditions for nasturtiums is the first step in ensuring they effectively contribute to the overall health of your vegetable garden.
