What are the effects of bat guano on polyethylene outdoor flower pot materials?

Bat guano, a natural fertilizer rich in nutrients, can have both positive and negative effects on polyethylene outdoor flower pots. While it enhances soil fertility, its high acidity and moisture retention may accelerate material degradation over time. Polyethylene, though durable, can become brittle or discolored when exposed to prolonged acidic conditions. Additionally, the salts in bat guano may leave residues that weaken the plastic's structural integrity. For long-lasting use, consider rinsing pots periodically or using protective liners to minimize direct contact with guano. Balancing its benefits and risks ensures healthy plants and durable containers.
