Can You Plant Onions, Cabbage, and Pomegranates Together?

Companion planting is a popular gardening strategy that involves growing different plants close to each other to enhance growth, deter pests, and maximize space. This article explores whether onions, cabbage, and pomegranates can be planted together, analyzing their compatibility and offering practical gardening tips.

Compatibility Analysis

The short answer is: No, onions, cabbage, and pomegranates are not ideal companions for each other. While onions and cabbage can often be good companions, pomegranates have different growth requirements that make them less compatible with these vegetables.

Onions and cabbage benefit from being grown together because onions can repel pests that commonly afflict cabbage, such as cabbage worms and aphids. Both onions and cabbage thrive in similar soil conditions and require full sun. However, pomegranates, being a fruit tree, have different spacing and nutrient needs, making them less compatible with these vegetables. Pomegranates require more space and have a different root structure, which can compete with the shallow roots of onions and cabbage for nutrients and water.
