Traditional control strategies are at this time inadequate in controlling Himalayan balsam in the UK. This is frequently as the plant grows in inaccessible areas or web sites of substantial conservation position where chemical and/or manual control is just not a possibility.
When you clear the balsam in June/July, you're likely to discover that new balsam vegetation germinate inside the cleared regions and will mature and flower rapidly within the warmer summer time soil.
