Can You Plant Onions, Lemongrass, and Pomegranates Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize space. Gardeners often wonder if onions, lemongrass, and pomegranates can be planted together. This article explores their compatibility and provides practical tips for successful planting.

Compatibility Analysis

Can onions, lemongrass, and pomegranates be planted together? The answer is both yes and no.
