1. Selective cultivation: Ants select and cultivate specific fungal species that are mutually beneficial. They may also discard diseased or unproductive fungal material to maintain garden hygiene.

2. Constant care and maintenance: Ants continuously tend to their gardens, removing debris, regulating temperature and moisture levels, and providing nutrients to the fungus. They may use their own waste products or other organic materials as fertilizer.

3. Chemical control: Ants produce antimicrobial compounds that inhibit the growth of harmful bacteria and fungi in their gardens. These compounds can be secreted by the ants themselves or by symbiotic microorganisms associated with the ants or the fungus.

4. Behavioral adaptations: Some ants have specialized behaviors that help keep the garden clean and healthy. For example, they may carry out "undertaking," where they remove dead or diseased ants from the colony, preventing the spread of pathogens. They may also engage in "grooming," where they clean and maintain their own bodies and those of their nestmates, reducing the risk of infection.

5. Social immunity: The collective behavior and cooperation within ant colonies help to maintain garden health. By working together, ants can quickly detect and respond to threats, such as disease outbreaks, and take measures to mitigate their impact on the garden.
