How does granite resist moss or lichen growth in shaded outdoor flower pots?

Granite is a popular choice for outdoor flower pots due to its natural resistance to moss and lichen growth, especially in shaded areas. This resistance stems from granite's dense, non-porous surface, which prevents moisture retention—a key factor in moss and lichen development. Unlike softer stones or porous materials, granite's hardness and smooth texture make it difficult for spores to attach and thrive. Additionally, granite's mineral composition, including quartz and feldspar, creates an inhospitable environment for organic growth. For gardeners seeking low-maintenance solutions, granite flower pots offer durability and aesthetic appeal while minimizing the need for frequent cleaning or chemical treatments. Its ability to withstand damp, shaded conditions makes it an ideal material for long-lasting outdoor planters.
