Aristotle suggested that ‘nature abhors a vacuum’; that wherever there is a void, nature will attempt to fill it with something. A couple of thousand years or so later, the author Michael Pollan paraphrased him by stating that ‘nature abhors a garden’; that wherever there is ordered human intervention in the plant world, nature will attempt to disrupt that order. Nearly twenty years of practical gardening experience (and fourteen years after the publication of ‘Allotted Time‘ a book documenting my initiation into allotments) has taught me much about the machinations of plants and gardens, their owners and the links between how we treat nature and how we nurture our ourselves and others. ‘Horror Hortus’ is an ongoing exploration of these links and those between photography and photosynthesis.
