We are listing below the ten best companion plants for peas.

1. Carrots

Carrots and peas both require cool and moist conditions to grow; hence, they are good companion plants.

The rhizobium bacteria live on the roots of pea plants. These bacteria get food from pea plants and, in return, convert the atmospheric nitrogen into a soluble form that roots can easily absorb. This process is called nitrogen fixation.

The process helps the farmers and gardens as they don’t need to add commercial nitrogen fertilizers to the soil.

So, in short, peas release nitrogen naturally in the soil, and carrots require nitrogen-enriched soil to survive. So, in short, it is helping carrot plants to thrive. On the other hand, carrot plants will lose the soil so that the roots of peas can soak the proper amount of water and grow properly.

So here, both carrots and peas are beneficial to each other and are considered the best companion plants. If you plant them together, you can harvest both peas and carrots in high numbers.

2. Potatoes

Potatoes are the next best companion plant you can grow with peas. Potatoes require nitrogen to thrive appropriately, which peas can provide naturally.

So, both the pea plant and egg plant mutually benefit each other. Hence, planting them can double up both the crops in your garden during harvest season.

5. Radishes
