        Ivy  (Hedera helix)

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.

What to do about ivy on walls and monuments? Remove it and risk damage to stone or leave well alone?  There is a churchyard case study here

        Common Ragwort (Jacobaea vulgaris, aka Senecio jacobaea)

 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 .

Fitzalan Wood, Chipping Norton (created by Green Gym in 2014-15): species planted

Ash dieback  : scientific name Chalara fraxinea, or now, more correctly, Hymenoscyphus fraxineus. The following illustrated description dates from 2013, a year after this disease arrived in Britain, and states that it more commonly affects mature ash trees. This is not the experience on our affected worksites.  What is ash dieback?  

In 2019, official publications seem to accept that the fight to check the spread of the disease is lost and seem to advise against unnecessary felling as there is a chance that this may destroy trees which ultimately prove resistant or give clues to recovery.


Chipping Norton Green Gym has worked on tree planting and garden and orchard development and maintenance, covering flowers, fruit and vegetables. At the town’s Fitzalan Wood, created by our group in 2014, we are increasing biodiversity and enhancing amenity value by sowing and planting suitable native wildflowers to supplement existing species which have sprung up naturally.

Happy Birthday

“Chippy” Green Gym is just one of around 140 in the U.K. The first one was founded back in 1998 and in February 2018 they invited us to join a twentieth birthday celebration.
