How does the porosity of WPC materials affect water retention and root health in outdoor tree boxes?
The porosity of Wood-Plastic Composite (WPC) materials plays a critical role in determining water retention and root health in outdoor tree boxes. WPCs, known for their durability and eco-friendliness, are increasingly used in urban landscaping. Their porous structure allows for controlled water absorption and drainage, preventing both waterlogging and excessive dryness. This balance is essential for healthy root development, as roots require adequate moisture without suffocation. High porosity enhances aeration, reducing the risk of root rot, while moderate porosity ensures consistent hydration. Understanding these dynamics helps in selecting the right WPC for tree boxes, promoting long-term plant vitality and structural integrity.
