Besides being aware of garden history, the expert needs a thorough knowledge of the current situation, a regard for the value that still exists, as well as detailed on-site research and survey in order to deal with garden renewal.

Recognition and interpretation of historical value are also dependent on environmental factors. Relatively intact gardens that are easy to research and document pose a straightforward resolution case for the designer. On the other hand, when territorial integrity has been impaired or the historic value transformed (built-in, overgrown, dilapidated, etc.) and fallen into ruins, the authentic renewal is a complex and responsible task since the monument conservation must properly be carried out alongside missing data supplementation or completion. Reconstruction of a garden or garden element can only occur if no other memory needs to be destroyed for its sake, and there are sufficient genuine pieces of information available. The Florence Charter mentions this: 'In principle, no one period should be given precedence over any other, except in exceptional cases where the degree of damage or destruction affecting certain parts of a garden may be such that it is decided to reconstruct it on the basis of the traces that survive or of unimpeachable documentary evidence" [20].

Landscape architecture is an applied science. According to the guidelines on the preparation of scientific publications in garden history, the results of the research are based on general preliminary studies of garden and landscape history, the research results and experiences of several decades, the exploration and analysis of authentic historical sources, and the site surveys and assessments.
