This is a non-native, very invasive plant. That was introduced to Britain in 1839 due to its exotic colorful attraction for parks and gardens. Since then it has rapidly spread especially along river banks and other damp nutrient-rich areas.
Himalayan balsam can produce around 800 seeds per stem. The viability of these seeds is approximately 3 years.
The clearance of Himalayan balsam is a fun and easy job that suite all ages.
The best time to pull it is when the stems are at least 50cm tall and before the flowers turn to seeds.
This can be between April and late June depending on the climatic conditions of the year.
July 2019, In the jungle we were rather late pulling up, they can grow up to 3 metres
Each plant can contain 800 seeds. When they are pulled up just leave them on sight (to not contaminate any other area)
The plant is mostly water, so within a day or two it starts to wilt down
