• Limes also enjoy full sun and need well-drained soil, though they are more drought-tolerant once established.
• Cosmos are sun-loving annuals that tolerate poor soil and require minimal water.

Pest Control and Nutrient Needs

• Tomatoes benefit from cosmos, as these flowers attract beneficial insects like bees and predatory wasps that help control pests.
• Limes and cosmos do not directly benefit each other in pest control, but cosmos can attract pollinators, aiding lime fruit production.

Spacing Considerations

• Tomatoes and limes need ample space for root and canopy growth, while cosmos can be planted closer together, filling in gaps without competing for resources.
