Control of Weeds

Japanese Knotweed

Japanese Knotweed is the most invasive plant in Guernsey. It spreads rapidly, especially next to streams and takes over native plants and flowers.

Information on Japanese Knotweed, specific information on the chemical control of Japanese Knotweed (for qualified spray operators) and the control of this plant in gardens (for amateur gardeners) can be downloaded below.

Honey Fungus

Honey Fungus or Armillaria is probably the most important killer of woody plants on the Island.

There has been some controversy in recent years about whether it is a serious parasite or a secondary invader. Honey Fungus used to be considered one species, Armillaria mellea, however recent research has shown that there are several species in the UK varying in their pathogenicity. Of the seven species found in Europe, some are highly parasitic causing serious plant disease whereas others are merely saprophytic living on dead wood

Noxious Weeds

The Noxious Weeds (Guernsey) Law, 1952 states that an occupier of land must not allow noxious weeds that are in flower or seed to grow on that land.

The noxious weeds specified in the law are Common Ragwort, Hemlock Water Dropwort, Spear Thistle, and Creeping Thistle.

A leaflet on noxious weeds can be downloaded below. It contains information on the control of these plants.
