Are Peas and Onions Good Companion Plants?

Companion planting is the practice of growing different plants together in the same space for mutual benefits. Some plants thrive when grown with certain plants, while others may inhibit each other's growth. In this article, we'll explore whether peas and onions make good companion plants.

Peas

Peas are a cool-season vegetable that grows best in temperatures from 60-75°F. They prefer rich, moist soil and benefit from regular watering. Peas also fix nitrogen in the soil, which makes them a great companion plant for other vegetables that require nitrogen. Additionally, they provide shade and ground cover for the soil, which helps retain moisture and suppress weeds.

Onions

Onions are a versatile vegetable that can be grown in a variety of soil types and temperatures. They prefer well-draining soil and require regular watering. Onions have a shallow root system and are sensitive to competition. They should be grown with plants that have a similar root system and do not require a lot of water. Onions also repel pests and can benefit neighboring plants by masking their scent.
