Why You Shouldn't Plant Peas and Onions Together

Peas and onions are two popular vegetables that are often grown in home gardens. However, there are a few reasons why you should avoid planting them together.

Let's get started!

Why You Shouldn't Plant Peas and Onions Together

There are a few reasons why you shouldn't plant peas and onions together.

First, onions release a chemical called allicin that can stunt the growth of peas. Allicin is a sulfur compound that has a strong odor. It is also a natural antibiotic that can help to protect onions from pests and diseases. However, it can also be harmful to peas.

Second, peas and onions have different nutrient requirements. Peas are nitrogen-fixing plants, which means that they can convert atmospheric nitrogen into a form that other plants can use. Onions, on the other hand, are heavy feeders that require a lot of nitrogen. If you plant peas and onions together, the peas may not be able to get enough nitrogen, which will stunt their growth.

Third, peas and onions attract different pests and diseases. Peas are susceptible to pests such as aphids, pea moth, and pea weevil. Onions are susceptible to pests such as onion maggot, onion fly, and leafminer. If you plant peas and onions together, the pests and diseases that they attract may spread to each other.

So, if you want to get the best possible yield from your peas and onions, it is best to avoid planting them together.
