Can You Plant Onions, Kale, and Kiwi Together?

Companion planting is a technique many gardeners use to enhance plant growth and deter pests. But can onions, kale, and kiwi thrive together? In this article, we’ll explore their compatibility, growth requirements, and the potential benefits and challenges of planting them together.

Compatibility Analysis

Can you plant onions, kale, and kiwi together? The short answer is NO. These plants have distinct growth requirements and may not be the best companions. Let’s dive into why they don’t work well together:

• Growth Requirements: Onions and kale are cool-season crops, while kiwi is a perennial vine that thrives in warmer climates. Their differing temperature needs make it challenging to grow them together.
• Pest Control: Onions can repel some pests, benefiting kale. However, kiwi requires different pest management.
• Nutrient Needs: Onions and kale have similar nutrient requirements, but kiwi’s needs are more demanding, potentially leading to competition for resources.
• Spacing: Kiwi vines require ample space to spread, which can overshadow and compete with the smaller onion and kale plants.
