What are the effects of prolonged shade on algae growth on marble outdoor tree boxes?
Prolonged shade significantly influences algae growth on marble outdoor tree boxes. Shade creates a damp, low-light environment ideal for algae proliferation, as it retains moisture and reduces natural UV exposure that typically inhibits algae. Over time, algae form green or black stains, degrading the marble's aesthetic and structural integrity. To mitigate this, regular cleaning, improved sunlight exposure, or protective sealants are recommended. Understanding these effects helps in maintaining marble tree boxes and preventing long-term damage.
