Oregano’s Allies: The Best Companion Plants for Your Herb Garden

Greetings from my little patch of garden paradise here in Wisconsin! As an avid gardener with over 20 years of hands-on experience, I’ve cultivated a passion for discovering compatible plant pairings that thrive together. Finding the perfect plant partnerships is an art – and some science. In this blog post, I’ll share my tips for companion planting with one of my favorite herbs: oregano.

Oregano’s pungent, earthy aroma and delicate purple flowers have graced my garden beds every year without fail. While oregano has undeniable appeal on its own merits, it also makes an excellent companion for many vegetables, herbs, and ornamentals. With proper planting techniques, oregano’s companionship can bolster flavors, deter pests, and lend aesthetic appeal to your garden landscape.

An Ode to Oregano: The Basics

Before diving further into suitable plant pairings, let’s start with an introduction to oregano itself. Oregano is a hearty perennial herb in the mint family that is relatively easy to grow and richly rewarding. The compact, bushy plant sports petite leaves throughout spring and summer, bursting with a woodsy, slightly peppery flavor. Left unharvested, delicate purple oregano flowers attract pollinators and beneficial insects to your garden in midsummer.

Benefits of companion planting with oregano

While oregano thrives in my native Wisconsin, gardeners across most regions can cultivate it successfully indoors or outdoors. The versatile herb prefers total sun exposure, well-drained soil, and moderate watering. Once established, the drought-resistant roots will spread gradually to form a flavorful ground cover. Prune back leggy growth as needed to encourage dense foliage production.
