What role does mulch play in pest management?

Mulch plays a significant role in pest management by acting as a barrier against pests. When applied to the soil surface, mulch creates a physical barrier that can deter certain pests from accessing the plants. This can help reduce the incidence of pest damage to crops and ornamental plants. Additionally, mulch can help to suppress weeds, which are potential habitats for pests, keeping the growing area cleaner and less attractive to various pest species.

Moreover, certain types of mulch can also support beneficial organisms that contribute to pest control, although that is not its primary function as a barrier. By limiting the access that pests have to plants, mulch serves as an important tool in integrated pest management strategies, promoting healthier plant growth and reducing the need for chemical interventions.
