Are Nasturtiums Good Companion Plants?

When it comes to gardening, companion planting is an important technique used to grow a healthy and fruitful garden. Companion plants are planted together because they work well with one another, either by helping each other grow or by repelling pests. One plant that is often discussed as a great companion plant is the nasturtium. But are nasturtiums good companion plants? Let's take a closer look.

1. Nasturtiums Repel Pests

Nasturtiums are known for their ability to repel certain pests from gardens. They contain a compound called benzyl isothiocyanate, which is toxic to some insects. This makes nasturtiums a popular choice for companion planting with other plants that are prone to pest infestation. For example, planting nasturtiums next to tomato plants can help keep away aphids, whiteflies, and spider mites that are attracted to the tomatoes.

2. Nasturtiums Attract Beneficial Insects

Not only do nasturtiums repel harmful insects, but they also attract beneficial insects to the garden. The bright, showy flowers of the nasturtiums attract pollinators like bees and hummingbirds which help pollinate other plants in the garden. Additionally, nasturtiums attract predatory insects such as ladybugs that feed on aphids, mites, and other pests.

3. Nasturtiums Improve Soil Health

In addition to repelling pests and attracting beneficial insects, nasturtiums also help improve soil health in the garden. They have a deep taproot that can break up compacted soil, allowing for better water and nutrient absorption by other plants. Nasturtiums also release nutrients into the soil as they decompose, which can be beneficial to the plants growing around them.

4. Nasturtiums Enhance Flavor

Nasturtiums are not only a beautiful addition to any garden, but they also have an edible flower that is full of flavor. The flowers have a spicy, peppery taste that can be used to enhance the flavor of salads and other dishes. Additionally, planting nasturtiums next to vegetables such as broccoli, cauliflower, and kale can help enhance their flavor.

Conclusion

So, are nasturtiums good companion plants? The answer is YES! Nasturtiums are a fantastic addition to any garden, whether you are planting vegetables, herbs, or flowers. They offer a wide range of benefits as companion plants, including pest control, attracting beneficial insects, improving soil health, and enhancing flavor. So, if you are looking to give your garden a boost this season, consider adding some nasturtiums to the mix.
