Invading berberis tamed

A berberis which has been growing at the Marks Hall Estate near Coggeshall in Essex has been dramatically reduced in size.  The plant which came from the Royal Botanical Gardens at Kew over 30 years ago had grown to more than 20ft across and 23ft high.  Curator at Mark Hall, Jonathan Jukes explained to Ken Crowther why they have had to hard prune the shrub.
