Peas are among the easiest vegetables to grow, making them a favorite for beginner gardeners. Not only do they taste great and pair well with a variety of foods, but they also adapt easily to different growing spaces—from containers and raised beds to traditional garden rows.

These cool-season legumes naturally enrich the soil by fixing nitrogen, which benefits many companion plants. In particular, peas thrive alongside other legumes like beans and lentils, increasing the overall nitrogen availability for nearby crops. Many vegetables grow better when peas or other legumes are planted in close proximity.

However, not all plants make good companions for peas. Some compete for vital nutrients, while others release chemicals that can hinder their growth. Companion planting—strategically placing plants that help each other flourish—can boost yields, reduce pests, and create a healthier garden environment. To keep your pea patch thriving, it’s important to know which plants to avoid as neighbors.

Onions

Onions can hinder the nitrogen-fixing ability of peas by releasing natural compounds that disrupt beneficial soil bacteria. They also have an extensive root system that competes with peas for water and nutrients.

Garlic

Like onions, garlic can interfere with pea plant growth by suppressing beneficial bacteria in the soil. Additionally, its strong root system may inhibit the expansion of pea roots, reducing overall plant vigor.

Leeks

It is often advised not to grow leaks near your beans because Leeks are another member of the allium family that can stunt pea growth by depleting the soil of nutrients. They also have a long growing season, which may interfere with the natural life cycle of peas.

Scallions

Green Onions are unfussy and grow well in most gardens. One would think that scallions are great to grow next to Peas; however, that is not the case. Scallions have shallow yet extensive roots that can interfere with pea root systems. They also require a lot of the same nutrients as peas, leading to poor growth for both plants when placed together.

Chives

Chives are one of the few perennial vegetables that can thrive in nearly all kinds of soil and weather conditions. These hardy plants are known for their slender, grass-like leaves and delicate onion-like flavor. Chives’ purple flowerheads can add a vibrant touch to any garden space and attract pollinators.

Although chives can deter pests, they also release substances that inhibit pea plant development. Their tendency to form dense clusters can also crowd out pea plants, reducing airflow and sunlight.

Tomatoes

Tomatoes are a garden favorite, but they’re also a magnet for hungry pests. While tomatoes don’t directly harm peas, they attract aphids, spreading diseases and weakening pea plants.

Larger critters like rabbits, squirrels, and deer often nibble on the leaves and fruit, making it difficult to protect your harvest. Even if wildlife isn’t an issue, tomatoes attract a variety of insects that can cause significant damage.

Peppers

Like tomatoes, peppers are nightshades that can draw aphids and other pests that may move onto nearby peas. Additionally, their preference for warm growing conditions can clash with the cool-season needs of peas.

Shallots

Shallots compete with peas for essential soil resources, making it harder for peas to thrive. Their ability to repel certain insects can negatively impact beneficial organisms that help pea plants flourish.
