Can You Plant Kale, Potatoes, and Plums Together?

Companion planting is an age-old gardening technique where certain plants are grown together to enhance growth, deter pests, and maximize garden space. In this article, we’ll explore whether kale, potatoes, and plums can be successfully planted together. You’ll learn about their compatibility, growing requirements, benefits, challenges, and best practices for planting.

Compatibility Analysis

Can you plant kale, potatoes, and plums together? The short answer is no. While kale and potatoes can be companion plants, plums, being a fruit tree, have different needs and may not thrive when planted too close to these vegetables.

Key Factors

• Growth Requirements: Kale and potatoes thrive in similar soil conditions and climates, making them compatible. However, plums require more space and different nutrient management.
• Pest Control: Kale can deter some pests that affect potatoes, but plums do not share these benefits.
• Nutrient Needs: All three have different nutrient requirements, with plums needing more space and deeper soil for root growth.
• Spacing: Potatoes and kale can be interplanted, but plums need significant spacing due to their size.

Benefits of Planting Together

• Pest Repellent Properties: Kale can help repel pests like cabbage worms that may affect potatoes.
• Improved Flavor or Growth: Potatoes and kale can mutually benefit from shared soil nutrients.
• Space Efficiency: Interplanting kale and potatoes can maximize space in a vegetable garden.
• Soil Health Benefits: Rotating these crops can improve soil health, although plums should be in a separate area.
