More Balsam

Needing a flat walk , I suggested a meander along the river at Low Sizergh. Apart from being an interesting walk past the old gunpowder works,  I wanted to have a look out for Himalayan balsam. Hoping not to find any, because the National Trust who own the land, promised us they would take care of it. 
I can report that we pulled up over 450 plants. Many with  seed heads  waiting to be dispersed. With each plant generating up to 800 seeds , that's a lot of plants we've helped to prevent. We cut off the heads of any plants with seeds and place them in a carrier bag to go home for the dustbin. Here is MrP waving his bag.
