Can You Plant Onions, Kale, and Chives Together?

Companion planting is a popular technique among gardeners aiming to maximize space and improve plant health. Onions, kale, and chives are commonly grown vegetables and herbs. But can they thrive together in the same garden? In this article, we’ll explore their compatibility, growing requirements, and the benefits and challenges of planting them together.

Compatibility Analysis
