Giant Hogweed Under Control On Playing Fields

Public Park, North of England

A burning issue 

Giant Hogweed sap can cause horrific burns and blistering of the skin when it comes into contact with it. This blistering can reoccur over months, or even years.

That’s why a client contacted us after discovering a Giant Hogweed infestation on playing fields in Lancashire, an area with several football pitches used by hundreds of children to play.

Safety is the priority 

After conducting a site survey and mapping the invasive species, we provided a detailed report of the issues and talked through the options to remediate the infestation and keep local children safe.

After erecting temporary steel fencing to keep the area secure while we worked, we applied herbicide to the area twice a year in early summer, killing the plants and depleting the seed numbers to reduce future growth. Herbicide plans for invasive species take several years to become fully effective – that’s why securing the area on a project like this one is so vital.

We also knew education was really important for children’s safety, so we left our contact details on-site and provided information for the clients to use to inform parents of the risks of Giant Knotweed.

Time to play 

After 4 treatment visits, the Giant Hogweed was under a satisfactory level of control. The plants were significantly depleted. 

We monitored the site for a further two years to ensure quality control, and to treat any regrowth needed. 

Now, the playing fields are much safer for the children, with the risk of harm from Giant Hogweed significantly reduced.
