Cucumbers offer multiple benefits when planted alongside kale. They provide valuable shade, shielding the kale plants from the scorching summer sun and heat stress. The cucumber vines act as a living mulch, aiding in moisture retention and reducing evaporation in the soil.

Additionally, the extensive root system of cucumbers helps improve drainage and aeration, benefiting the growth of kale. As cucumbers decompose, they release valuable nutrients into the soil, providing natural fertilization for kale. Furthermore, the vertical growth habit of cucumbers maximizes growing space in the garden when planted alongside kale.

10.Calendula: Attracting Pollinators And Beneficial Insects

Calendula is a fantastic companion plant for kale, as it not only adds beauty to your garden but also attracts pollinators and beneficial insects.
