The Elements of Organic Gardening written by Prince Charles, was published this month. Prince Charles has invested his organic principles in his garden at Highgrove for years. So the systems described in the book are tried and tested!
The book is available from Amazon, who describe the book as follows:

‘For twenty-six years, the Prince of Wales has passionately honed the organic practices used at Highgrove, Their Royal Highnesses’ family home in Gloucestershire, as well as in his other gardens at Birkhall in the Scottish Highlands and Clarence House in central London. Now, alongside Andrew Lawson’s elegant photographs and with Country Living gardening editor Stephanie Donaldson, the Prince’s vivid elucidation of his techniques for maintaining healthy

soil, planting varieties, and sustaining an ecosystem “in harmony with the natural laws and rhythms of the universe of which we are an integral part” offers a wealth of wisdom to delight and inspire any gardener. His practices, based on a deep respect for nature, can be adapted to almost any garden, large or small. The Prince is hands-on in his gardens, and it is this passion that reveals itself intimately to be at the heart of The Elements of Organic Gardening. 200 full-color photographs.’
