Himalayan balsam can be controlled by spraying the foliage with glyphosate. The plants should be sprayed in the spring before flowering but late enough to ensure that germinating seedlings have grown up sufficiently to be adequately covered by the spray. Glyphosate is sold under a number of brand names.

Can I strim Himalayan balsam?
Strimming. Strimming is a good option where stands are dense, and where the ground is reasonably level. Care should be taken to strim the plant below the first node, as it will otherwise re-grow and flower later in the season. Strimmed plants can be left on site to compost, but only if the seed pods have not yet formed ...

What is the problem with Himalayan balsam?
But Himalayan balsam is a problematic plant. It competes with native plants for light, nutrients, pollinators and space, excluding other plants and reducing biodiversity. It dies back in the winter, leaving river banks bare and open to erosion.
What kills Himalayan balsam?
Small infestations and individual plants can be controlled by using glyphosate in a weed wiper. This has the advantage of minimising herbicide effects on non-target species. The herbicide 2,4-D amine controls many broadleaved annual weeds and can be used on Himalayan balsam.
Is Himalayan balsam dangerous?
Himalayan balsam presents no physical danger to either humans or animals. It does, however, provide a significant ecological impact since it grows in dense stands that suppress native grasses and other flora. In the autumn the plants die off leaving riverbanks bare and highly susceptible to erosion.
How long do Himalayan balsam seeds last?
Persistence and Spread: The seeds can remain viable for up to 2 years but Himalayan balsam does not form a persistent seedbank in soil. The seedpods are dehiscent and explode when touched or shaken.

How do you propagate Balsam?
Propagating Balsam Flowers
The seeds sprout in as little as four days in moist soil at 70 degrees Fahrenheit. Start them indoors about eight weeks before your average last frost, planning for about 60 days from seed to first bloom. Light hastens germination, so don't cover the seeds with soil.
