Plants to Avoid Planting Near Peas

While peas are compatible with many plants, there are certain plants that should be kept away from them to ensure optimal growth and health.

Understanding which plants are not conducive to the well-being of peas is crucial in companion planting.

Here are some key plants to avoid when planting peas:

Onions and Garlic

  Both onions and garlic belong to the allium family and are known for their allelopathic properties, meaning they release chemicals that can inhibit the growth of peas and other plants.

• Competition for Resources:

  These plants can also compete with peas for essential nutrients in the soil, potentially stunting the growth of your pea plants.

Potatoes

• Disease Risk:

  Potatoes can increase the risk of blight and other diseases that can also affect peas.

  These diseases can easily spread from potatoes to peas, especially in damp conditions.

• Nutrient Competition:

  Potatoes are heavy feeders and may compete with peas for nutrients, particularly in soils that are not rich in organic matter.

Other Plants to Consider

• Gladiolus and Chives:

  Like onions and garlic, gladiolus and chives can also have adverse effects on peas.

• Fennel:

  Fennel is known to be a poor companion for most plants, including peas, due to its strong allelopathic tendencies.
