In this feature documentary for BBC2, Alan Titchmarsh and Prince Charles explore the gardens of Highgrove House; a personal tour of HRH’s sanctuary and private home. This is a rare Royal invitation, and never before has the Prince given up so much of his time to tell the story of his passion project. Alan discovers why this estate of rare beauty and purity of purpose has become iconic for all things organic, and finds out what it has been like to deal with decades of gardening criticism. In this remarkably candid interview, we discover what Highgrove means to the man who will be King.
