The Compleat Gard’ner was published posthumously and translated for the English edition by John Evelyn who included a section on orange trees not included in the original French edition. The text is available on-line

A lot of the articles are pretty basic e.g. how long the sides of gardens should be and how wide the footpaths and arrangements for watering.

Others are more detailed. Here is an excerpt on grafting which Quintinye calls graffing
‘The most common and best Method of Graffing, is either cleftwise, or Scutcheonwise: The first in February or March upon Trees from the Thickness of an Inch Diameter to Ten and Twelve Inches Circumference, and even more: This way of Graffing is good for all manner of Fruit Trees, excepting only Peach, Almond, Mulberry, Fig-Trees, &c. upon which it seldom succeeds.
[the etc here rather leaves the reader in limbo]
As to the Scutcheon Graff for Stone and Kernel-Fruit, if it be at the Time of shooting, it must be perform'd about Midsummer; if at the closure of the Eye, and upon Plum, Pear and Apple-Trees, about the middle of August; and upon Peach and Almond Trees, towards the middle of September; that is, both on the one and the other it must only be done about the Declining of the Sap.

It is interesting to search this out online. It is on a site called Early English Books online.
