Can You Plant Tomatoes, Plums, and Kiwi Together?

Companion planting is a popular gardening technique where different plants are grown together to enhance growth, deter pests, and maximize space. In this article, we explore whether tomatoes, plums, and kiwi can thrive together and provide practical tips for gardeners considering this combination.

Compatibility Analysis

Can you plant tomatoes, plums, and kiwi together? The short answer is NO. These plants have different growth requirements and may not be the best companions. Let’s dive into the details.

Growth Requirements

• Tomatoes: These sun-loving annuals require warm temperatures, well-drained soil, and consistent watering. They thrive in acidic to neutral soil with a pH of 6.0 to 6.8.

• Plums: As fruit trees, plums need full sun and well-drained soil. They prefer slightly acidic to neutral soil with a pH of 5.5 to 6.5 and require a cold winter period to produce fruit.

• Kiwi: These vining plants need sturdy support, full sun, and well-drained soil. They prefer slightly acidic soil with a pH of 5.0 to 6.8 and require a long growing season.

Key Factors

• Pest Control: Tomatoes can deter some pests from plums, but kiwi and tomatoes may attract similar pests like aphids.

• Nutrient Needs: All three plants require rich, fertile soil, but their specific nutrient needs differ, which can lead to competition.

• Spacing: Tomatoes need space to spread, while plums and kiwi require ample room for their roots and vines, respectively.
