Cutting balsam

video

Unlike most invasive plants, Himalayan balsam can be effectively controlled without using chemicals. Scattered plants can be uprooted, while dense stands can be cut using a Martindale weed slasher.

  1. BTCV volunteers have also been using this method in areas where the balsam is occurring in dense stands...however in dry areas where there is a lot of old wood and dead trees about they have been encountering a high number of wasp nests which are less than pleasant to you when your swiping around their nest with a slasher! Anyone else encountering a higher than normal volume of wasp nests in areas where they are controlling HB?

  2. Yes, wasps are a problem in Glenurquhart too. A long-bladed slasher and fast running shoes recommended!
