Knowle Hill balsam clearance

The second of two sessions working in the grounds of Knowle Hill, a Landmark Trust site near Ticknall, clearing invasive Himalayan balsam from the woodland slopes. The traditional method has been to pull up the balsam once it has fully established, usually around June/July, but in 2019 we started an experiment at Knowle Hill to remove the balsam at its seedling stage in March/April by raking and hoeing. More details and pictures are in this report by Lawrence. We were unable to continue with the trial in 2020 due to the Spring lockdown, so we have belatedly resumed it this year.
