yes Hugo I think you raised the big problem of science at the moment many things are evaluated in laboratory or experimental plots that sometimes use up to the sterilization of the soil by steam to limit the unknown parameters of the life of the soil which could confuse a study result.
A garden is not that, all are already different with controllable parameters such as the composition of natural soils, practical, cultivated plants… etc
There are also parameters that will never be controllable: weather, chemical elements that arrive by rain, an exogenous bacterium that you could have brought back from a sample of land that you bring back from your vacation, the history of your plot…
On paper, with common sense and according to scientific research, local plants with local bacteria are the winning duo… but everything is so unpredictable in life and plants !
Yet I am connected with botanical gardens and collection, and I can tell you for a completely obscure reason and I would like to understand the reason : rare plants and trees from the South USA: California, Arizona, New Mexico, Texas, and North Mexico: Baja California, Sonora, Chihuaha, Cohahuila are very sprouting plants (see more than in their natural environment) in several gardens in France and Western Europe.
Yet we do not share the same latitude that corresponds more to that of Tunis, not the same microfauna fungi bacteria (plants are imported in seeds without soil), not the same climate or soil…
With so much interest, I became particularly passionate about the plants of this place of the world. I introduce them and gathered here to make a garden partly dedicated to better study them…and I feel a very good vibrations in their company!
So why? my intuition, plants are very opportunistic and evolutionary
We are experiencing a great climatic upheaval, plants are under stress in many natural environments of the planet and have begun survival processes (migration, mutation, introgression…)
These regions are a hot spot of biodiversity because they are the crossroads and starting point between what migrated north or south. Today it is a meeting point and a dead end, the things of the North migrate south and that of the South to the North by finding themselves stuck on this central zone.
The plants are thus stuck down and certainly put mechanisms of exceptional survival still unknown to take advantage and the opportunity of the man who moves them. As the domestication of humans by plants (and not the opposite which sponsored so logical) remains a track of work of some researchers. For having already spoken about, neurobiology of plant is something whose advances are spectacular and really disturbing (cf Stefano Mancuso).
There could also be a reason related to the fact that this place of the earth has already received one of the biggest upheaval that the earth is known with the fall of the asteroid that created the Gulf of Mexico. Such amount of energy, radiation… certainly still have an impact millions of years later in the genetic memory of these plants…
All this to tell you Hugo that we do not know much about plants with our 46 chromosomes (the vegetable equivalent of the Olive tree). Some plants have arrived at forms of evolution so complex that a Morus nigra with 308 chromosomes, and 1440 for a fern that holds the record. This genetics must have a purpose, but are we evolved enough to understand?
The only choice left for us to observe, experiment, document… to try to re-establish connections with the extraordinary world of other living beings who have never lost this ability.
Ps: for pascal poot, no I do not use these seeds, because I make mine and never water the tomatoes once in the ground. The seeds of this gentleman must above all have a sacred genetic memory of the organic matter that he brings in unreasonable quantity. They would not necessarily be well at first with my unfertilized clay soil.
