Can You Plant Celery, Oregano, and Parsley Together?

Companion planting is a popular strategy among gardeners that involves growing plants together to enhance growth, deter pests, and maximize garden space. In this article, we’ll explore whether celery, oregano, and parsley are compatible companions, what benefits they may offer each other, and how to successfully plant them together.

Compatibility Analysis

The short answer is yes, you can plant celery, oregano, and parsley together. These plants complement each other well, with similar growth requirements and the ability to enhance each other’s flavors while deterring certain pests. Celery requires a good amount of water and nutrient-rich soil, which oregano and parsley can tolerate. Oregano, with its aromatic leaves, can repel pests that might otherwise be attracted to celery and parsley. Parsley, being a biennial, can grow alongside these plants without competing aggressively for resources.
