Key ID Features

Himalayan balsam spreads through the production of seeds which it catapults up to 7 metres away with its explosive seed pods. The plant material does not re-generate into a new plant.

Himalayan balsam (Impatiens Glandulifera)

Stems are hollow and jointed, sappy and brittle, pinky-red colour.

Often grows in dense stands

  • Spraying with a commercial glyphosate-based chemical is effective with Himalayan balsam being controlled in 2-3 years. The plant should be sprayed when the leaves are fully out but before flowering. Any re-growth can be sprayed later in the season

  •  Cutting stems or pulling with roots before the plant sets seed is succesful. Grazing is an efficient way of controlling Himalayan balsam

  • Himalayan balsam can be disposed of by leaving the plants out to dry or by burning.
