How does archaeology play into historic horticulture?
Archeologists are looking for postholes, paths, wall remains, and fence post remains, so at least we can start understanding the actual enclosure. What was the size? What were the bones of the garden? Then beyond that, and I think they will concur with this, that garden archaeology is not easy, because they're not looking for physical items necessarily. They're looking for different soil horizons, and that's hard. When they were digging the upper garden, back 10 years ago or more, they found every horizon of every different garden. But that didn't come without digging it for a year or two before they could really even start to recognize them, so it’s really, really difficult. You've got to have the knowledge base before you can even begin. Then things start to make sense.
