Can You Plant Celery, Fennel, and Nasturtiums Together?

Introduction

Companion planting is a popular gardening technique that pairs plants to enhance growth, deter pests, and improve flavor. Celery, fennel, and nasturtiums are often considered for this method. In this article, you’ll learn whether these plants are compatible and how to optimize your garden space.

Compatibility Analysis

The question of whether you can plant celery, fennel, and nasturtiums together is a nuanced one. The short answer is: yes, but with some considerations. Celery and nasturtiums make a good pair due to their complementary growth habits and pest-repellent properties. However, fennel can be a challenging companion plant because it tends to inhibit the growth of many other plants, including celery.

Growth Requirements

• Celery thrives in cooler temperatures with consistent moisture and benefits from nasturtiums’ ability to repel aphids.
• Nasturtiums are low-maintenance and can attract beneficial insects, making them a good companion for celery.
• Fennel, while a beautiful and aromatic plant, can secrete a substance that inhibits the growth of its neighbors, making it less ideal for companion planting with celery and nasturtiums.
