Hannah Stephenson traces the history of the BBC's popular TV series.
It started as a seed of an idea when colour TV was just coming in. But Gardeners' World celebrated its 40th year with an hour-long special on BBC Two which reflected how trends have changed over the years, from the formal bedding of the 1960s and 1970s to the present wave of naturalistic planting and wildlife-friendly spaces.
The first programme was filmed using guest gardens, with Percy Thrower, and broadcast on January 5, 1968. The following year he began using his own garden, Magnolias, in Shrewsbury, for the series.
