One popular companion plant for squash is the nasturtium, a vibrant, edible flower that can serve as a living mulch. Using nasturtiums as a living mulch for butternut squash offers numerous benefits, including weed suppression, pest deterrence, and improved soil health.
Benefits of Using Nasturtiums as Living Mulch
- Weed suppression: Nasturtiums spread quickly, covering the soil and preventing weed growth.
- Pest deterrence: The strong scent of nasturtiums can repel pests such as aphids and squash bugs.

Planting Nasturtiums with Butternut Squash
To successfully use nasturtiums as a living mulch, plant them around the base of your butternut squash plants early in the season. Choose a sunny location with well-drained soil. Sow nasturtium seeds directly into the ground after the last frost date, spacing them about 12 inches apart. Allow the nasturtiums to spread naturally, covering the soil around the squash plants.
Maintenance Tips
Ensure that nasturtiums receive adequate water, especially during dry spells, to keep them healthy and vigorous. Deadhead spent flowers to encourage continuous blooming. Monitor for pests and diseases, and remove any affected plant material promptly. As the nasturtiums grow, they will create a natural barrier that benefits your butternut squash crop.
Harvesting and Uses
Harvest the vibrant flowers and tender leaves of nasturtiums for culinary use. They add a peppery flavor to salads, garnishes, and sandwiches. Incorporating nasturtiums into your garden not only enhances aesthetics but also enriches your harvest with edible delights.
Conclusion
Using nasturtiums as a living mulch for butternut squash is an effective, eco-friendly gardening practice. It promotes healthy plant growth, reduces weeds, and attracts beneficial insects.
