The Real Story About Worm Casts
Earthworms are considered a ‘beneficial species’ due to the good work they do recycling nutrients within the soil. However, as of September 2017 there are no chemical controls for casting earthworms approved for use on golf courses, leaving greenkeepers with a dilemma as to how to combat them.
The British and International Golf Greenkeepers Association Ltd (BIGGA) have produced an information poster and a four page leaflet discussing this issue. Please use the links on the left to download these materials.
