The first is:

The Compleat Gard’ner.

This book from 1693 was a real find. My computer library search had completely missed this book because of the ways in which Complete and Gardener are spelt. It was just routine scanning of the shelves that found it.
The compleat gard'ner, or, Directions for cultivating and right ordering of fruit-gardens and kitchen-gardens with divers reflections on several parts of husbandry, in six books : to which is added, his treatise of orange-trees, with the raising of melons, omitted in the French editions / by the famous Monsr De La Quintinye ... ; made English by John Evelyn ... ; illustrated with copper plates.

In the 1660s Louis 14th had decided to turn his father’s hunting lodge at Versailles into a palace. He hired Jean –Baptiste de La Quintinye to design and look after the fruit and vegetable garden. His title was Potager.
