The Himalayan balsam, also known as Indian balsam, dies in winter, but its seeds survive and with it it becomes a nuisance weed. How can it be combated effectively and permanently?

Balsam multiplies very quickly and is therefore not desirable everywhere

Why should we fight balsam quickly?

Whether in the garden or on riparian zones throughout Germany - this balsam causes a stir. Why actually?

  • neophyte
  • crowds out native plants
  • can grow fast (weeds)
  • Seeds can germinate for many years
  • is poisonous

Fight before seed maturity

Impatiens should be controlled in spring by July at the latest. Its flowering period begins in July and the seeds have formed shortly thereafter. This is to be avoided! Once the seeds are ripe, they are soon catapulted out of the fruit capsules and scattered in all directions.

Manual combat

The best way to control Balsam is to uproot the entire plant. This is usually easy - especially if the soil is moist - when there are only a few plants. Balsam has shallow roots and the small roots can be easily removed. Pull the plant out by grabbing the bottom end of the stem and pulling firmly.

Mow or scythe large stands

If there are large stocks that you want to destroy, it is better if you mow or scythe the plants. Never dispose of the waste in the compost, but always in the household waste. Otherwise, the seeds will survive and spread later.

Chemical control

Chemical control of balsam is not recommended. On the one hand, balsam is easy to remove manually and only its seeds are 'dangerous'. On the other hand, herbicides damage the environment, especially when they are used at the water's edge and carried away by the water.

prevent spread

Since it can sometimes take several years before balsam has been combated effectively and 100% (the edible seeds can germinate for many years), it is advisable to prevent it from spreading:

  • do not plant near water
  • do not sow outdoors
  • cut before seed ripening
  • carry out regular inspections

tips

It's a good practice to starve the balsam. Its nutritional requirements are extremely high. Never fertilize the plant and it will eventually die.
