During Green Gym sessions, we sometimes remove ivy from trees. But how necessary is it to do so? See what the Royal Horticultural Society says, here.

 Ragwort is a valuable source of nectar and pollen to many insects, and a food plant for some caterpillars, but can be dangerous to livestock. 

There is a brief description of the plant, associated risks, and non-chemical control here. For  fuller information on ragwort, with a “Facts or Myths?” section, visit .
