Compatibility Analysis

Can you plant broccoli, potatoes, and mint together? The short answer is no, these plants are not ideal companions. While mint can be beneficial in repelling certain pests, its aggressive growth can overwhelm other plants. Broccoli and potatoes are both heavy feeders and can compete for nutrients, making them poor companions.

Growth Requirements

• Broccoli prefers cool weather, full sun, and well-drained soil with a slightly acidic to neutral pH.
• Potatoes thrive in full sun and loose, well-drained, slightly acidic soil.
• Mint is versatile, growing in full sun to partial shade, and prefers moist, well-drained soil.

Pest Control and Nutrient Needs

Mint can deter pests like aphids, but its invasive nature can overshadow its benefits. Broccoli and potatoes both attract similar pests, such as cabbage worms and potato beetles, which can complicate pest management.
