2. Pest Control

• Marigolds are aphid and nematode repellents.
  
• Herbs like basil and thyme can confuse pests due to their strong fragrance.
  

3. Pollinator Attraction

• Calendula and nasturtium flowers are attractive to bees, and boost the production of fruit and pollination by aubergines.
  

4. Microclimate Benefits

• Plants with tall heights like Jerusalem artichokes or corn provide a soft shade for aubergines in hot climates.

In a 2×3 meter garden bed:

• Six aubergine plants were planted with marigolds, basil and a few spinach.
  
• The results: Basil reduced flea beetles and marigolds ward off nematodes. greens covered soil and yields were up by 25% when as compared to monoculture plants.
  

This illustrates how easy methods of companionship can alter the harvest results.
