Benefits of Planting Together

While planting cauliflower, cabbage, and kiwi together isn’t recommended, pairing cauliflower and cabbage can offer benefits:

• Pest Repellent Properties: Planting marigolds nearby can deter pests common to both.
• Improved Flavor and Growth: Both benefit from the same soil amendments, enhancing flavor and growth.
• Space Efficiency: Interplanting with herbs like dill can save space and improve soil health.
