In February of 2014, I was invited to prune the gardens at Sissinghurst Castle. One of the most famous English gardens, it was created in the 1930's by Vita Sackville-West, a poet and garden writer, and her husband, Harold Nicholson, an author and diplomat. Even in the dead of winter the garden is stunning, as evidenced here by the famous Lime Walk composed of pollarded and grafted linden trees framed by a pleached hedge of hornbeam. Artful and magnificent despite being leafless. Winter, the best time to study pruning.
