Xylella fastidiosa, commonly referred to as Xylella, is a bacterial pathogen that poses a significant threat to various plant species around the world. It infects the xylem. The water-conducting tissues of plants, leading to blockage of water transport and ultimately causing severe damage or death to infected plants.

The symptoms of Xylella fastidiosa vary depending on the host plant species and the strain of the bacterium. In some cases, infected plants may exhibit leaf scorching, wilting of yellowing of the leaves. Other symptoms can include stunted growth, dieback of branches and eventful plant death.

Xylella represents a significant challenge for agriculture, horticulture and forestry worldwide. Its ability to infect a wide range of plant species, its potential for rapid spread, and the difficulties associated with its control make it a priority for plant health management.

Currently, there are areas of Europe that are infected with Xylella, but no detection in the UK. The risk of introduction however, is extremely high. Our industry needs to do everything within its power to stop Xylella from entering the UK.

Here at Hillier Trees, we operate a zero-tolerance approach to biosecurity and will not import trees that are a host to major pests and diseases from infected areas.
