Gardens in the broadest sense date to the beginning of small-scale agriculture, and decorative gardening is as old as royal palaces and great houses, going back millennia in Egypt and China. However, little is known about gardening as a profession before the explosion of literacy at TL4. This template represents a plausible working low-tech gardener with some knowledge of technical details, not an upper-class hobbyist (and not the artistic landscape gardeners who appear at TL4 or TL5).
