What should not be planted near peas?

Answered by James Kissner

When it comes to planting peas, there are a few plants that you should avoid growing nearby. One group of plants that can have a negative impact on peas are alliums, including onions, garlic, and chives. These plants release certain compounds into the soil that can stunt the growth of peas.

I learned this the hard way when I planted peas next to my onion patch one year. The peas seemed to struggle right from the start. They grew slowly and their leaves appeared pale and stunted. It took me a while to realize that the close proximity to the onions was the problem.

Alliums release sulfurous compounds as they grow, which can inhibit the growth of nearby plants. These compounds can interfere with nutrient uptake and affect the overall health and development of plants. In the case of peas, planting them near alliums can result in stunted growth and reduced yields.

To avoid this issue, it is best to keep your peas and alliums separate in the garden. If you have limited space, you can consider using containers or raised beds to keep the plants apart. This way, you can enjoy both the delicious taste of fresh peas and the aromatic flavors of onions or garlic without any negative effects on their growth.

It’s important to note that this doesn’t mean you can’t grow peas and alliums in the same garden at all. You just need to ensure that they are planted far enough apart that the alliums’ compounds won’t affect the peas. The exact distance will depend on the specific plants and their growth habits, so it’s a good idea to do some research or consult a gardening guide for specific recommendations.

In addition to alliums, there are a few other plants that may not be the best companions for peas. Legumes, such as beans and lentils, can sometimes compete for similar nutrients and may not grow as well when planted too close to peas. Similarly, brassicas like cabbage and broccoli may not thrive when planted near peas, as they have different nutrient requirements.

To summarize, it’s best to avoid planting peas near alliums like onions, garlic, and chives, as their sulfurous compounds can stunt the growth of peas. If you want to grow both peas and alliums in the same garden, make sure to keep them sufficiently separated. Additionally, be cautious when planting peas near legumes or brassicas, as they may have different nutrient requirements and could potentially compete for resources. By being mindful of these planting combinations, you can ensure optimal growth and harvest for your peas.
