Removal and Control of Floating Pennywort

The plant is difficult to control as the smallest fragment can lead to the plant re-establishing.

Mechanical removal is best but the area should be netted off to prevent plant fragments from travelling downstream. Once the main bulk has been removed it is important to go over the area and remove all smaller fragments to prevent spread.

Chemicals can be used but only by those with suitable training.

Floating Pennywort should be reported via the Recording Native Species Counts scheme.
