Can You Plant Onions, Kale, and Plums Together?

Companion planting is a popular gardening technique where different plants are grown together to enhance growth, deter pests, and maximize garden space. When considering planting onions, kale, and plums together, understanding their compatibility is crucial. This article explores whether these plants can thrive side by side and offers practical tips for successful companion planting.

Compatibility Analysis

Can you plant onions, kale, and plums together? The answer is both yes and no. While onions and kale can be excellent companions due to their complementary growth habits and pest-repelling properties, plums are a different story. Let’s delve deeper into the reasons behind this compatibility (or lack thereof).

Onions and Kale

Onions and kale are compatible companions. Onions, with their strong aroma, can deter common pests like aphids and cabbage worms that typically target kale. Both plants have similar growth requirements, such as full sun and well-drained soil, making them suitable to grow together in a vegetable garden.

Plums

Plums, on the other hand, are fruit trees with different growth requirements and space needs compared to onions and kale. While you can plant them in the same garden, they should be strategically spaced to avoid competition for sunlight and nutrients. Plums have larger root systems and require more space, which can overshadow and hinder the growth of smaller plants like onions and kale.
