Does WPC affect mycelium networks in a landscape tree box?
Wood-Plastic Composite (WPC) is increasingly used in urban landscaping, including tree boxes, due to its durability and low maintenance. However, its impact on mycelium networks—critical for soil health and tree vitality—remains a topic of debate.
Mycelium, the fungal network beneath the soil, facilitates nutrient exchange and supports tree resilience. WPC, being a synthetic material, may alter soil moisture and temperature, potentially disrupting mycelial growth. Studies suggest that WPC can create a barrier, limiting fungal colonization and reducing organic decomposition rates.
To mitigate these effects, consider using WPC with natural additives or spacing it away from root zones. Integrating organic mulches or mycorrhizal inoculants can also help sustain mycelium activity. Balancing WPC’s benefits with ecological harmony is key for sustainable urban forestry.
Further research is needed to optimize WPC designs that coexist with soil ecosystems, ensuring healthy mycelium networks and thriving urban trees.
