You would probably encounter Himalayan Balsam on riverbanks, alongside watercourses, around garbage strategies and in waste ground. What's more, it grows on forest and woodland edges, in fields and meadows and all around ditches.
Outbreaks – An environmental or human function which leads to a unexpected random infestation of Himalayan balsam which might require a rapid reaction depending upon the spot inside a project space.
In certain parts of the Northern Hemisphere Himalayan Balsam has actually been declared an invasive species. It's got fast colonised river banking companies, excluding indigenous species by Level of competition and forcing some parts of the united kingdom to introduce eradication procedures.
A source infestation may very well be in proximity to drinking water creating broader spread within just that catchment and or an isolated ‘satellite’ infestation inside the early levels of wider landscape invasion.
Flowering might differ from year to period, and also with microclimate (You can find suggestion, such as, that vegetation expanding at lessen altitude or nearer to the sea may well set seed earlier than plants developed bigger up). The seeds aren’t fashioned until eventually August/September.
When you have eradicated Himalayan balsam with the lender of the river, stream or ditch, look at incorporating a plant with roots that should help to stabilise the soil; for Strategies see our internet pages on steep financial institutions and slopes and financial institution and ditch habitats.
Weeds need to be completely wetted With all the spray Answer, but spraying till "run-off" will minimize exercise. The usage of lower drift nozzles is suggested to stop drift onto attractive vegetation.

Spray when great foliage has produced into a peak of no less than fifty cm in late spring, ahead of the close of June. A next procedure can be important if extra seedlings germinate
Control of Himalayan Balsam must ideally happen in the event the vegetation have grown to a great top, but haven't but flowered. This is generally around June.
Satellite infestation – A region of balsam isolated from a wider infestation as a consequence of early invasion. You will discover regions of land or h2o in proximity to your satellite infestation in here which no balsam is existing but still left uncontrolled the satellite is likely being the supply in these areas by means of all-natural or manmade dispersal pathways.
Our gardens are enriched from the introduction of crops from abroad, but a little number have proved hugely invasive in britain. Listed here we offer a list of invasive non-indigenous species and knowledge on how one can enable control their spread.
Location infestation – An area of land highlighted as having balsam existing, both dense or sporadic. an area of land highlighted for balsam infestation that may be sporadic in that region or dense infestation (the area to control and watch). That is recorded making use of GIS read more polygons.
They should below no conditions be taken off internet site and disposed off in usual compost, or at a read more traditional squander disposal station.
