Can You Plant Onions, Cabbage, and Kiwi Together?

Companion planting is a gardening technique that many gardeners use to maximize space and improve plant health. In this article, we’ll explore whether onions, cabbage, and kiwi can be grown together, examining their compatibility and offering practical tips for success.

Compatibility Analysis

The short answer to whether you can plant onions, cabbage, and kiwi together is NO. While onions and cabbage can be compatible companions, kiwi is not well-suited to be grown with these vegetables. Let’s delve into why this is the case by examining their growth requirements, pest control benefits, nutrient needs, and spacing considerations.

Onions and Cabbage

Onions and cabbage are often planted together due to their complementary growth habits and pest-repellent properties. Onions can help deter pests like cabbage worms, which are common in cabbage plants. Both require similar sunlight and water needs, making them compatible companions in a vegetable garden.

Kiwi

Kiwi, on the other hand, is a fruit-bearing vine that requires a different set of growing conditions. It needs a sturdy support structure, ample space to spread, and a longer growing season. Kiwi’s growth habit and nutrient requirements differ significantly from those of onions and cabbage, making it an unsuitable companion for these vegetables.
