Understanding the characteristics of your rocks will help you choose the most appropriate cleaning method and avoid damage.

7. Preventing Future Fungus Growth on Rocks

Prevention is key to keeping your rocks fungus-free. Here are some tips to prevent future fungal growth:

Improve Drainage: Ensure proper drainage around your rocks to prevent water from pooling and creating a damp environment.
Increase Sunlight Exposure: Trim back vegetation to allow more sunlight to reach the rocks, as sunlight inhibits fungal growth.
Regular Cleaning: Clean your rocks regularly to remove dirt, debris, and fungal spores before they have a chance to take hold.
Apply a Protective Sealant: Consider applying a protective sealant to your rocks to create a barrier against moisture and fungal growth.
Use Fungicide Sparingly: Use fungicides only when necessary and follow the manufacturer’s instructions carefully to avoid harming beneficial organisms.
