Pea plants growing with companion plants in a garden

As a professional gardener based in Staffordshire, I've spent over 15 years cultivating various vegetables, and peas have always been a favourite. They’re easy to grow and can be quite rewarding. However, to make the most out of your pea plants, companion planting is key. Let’s explore what works best alongside peas.

Quick Answer

Best companion plants for peas include carrots, radishes, and mint. Avoid planting peas near onions and garlic.

Benefits of Companion Planting with Peas

Companion planting can significantly improve the health and yield of your pea plants. Here are some benefits:

  • Enhances soil fertility and structure
  • Improves pest control naturally
  • Maximises space and productivity

Top Companions for Peas

Carrots

Carrots and peas are a classic combination. Carrots help to aerate the soil, which benefits the peas' root systems. Plant carrots about 5 cm apart from your peas.

Radishes

Radishes grow quickly and can be harvested before the peas need more space. They also help deter certain pests that might otherwise affect your peas.

Mint

Mint is excellent at repelling pests that tend to target peas. However, mint can be invasive, so consider planting it in pots nearby rather than directly in the soil with your peas.

Plants to Avoid Near Peas

Some plants are better kept away from peas as they can inhibit their growth:

  • Onions and garlic can hinder pea growth
  • Chives, being related to onions, offer similar drawbacks
