what goes into planting an oak tree

The more familiar you are  with a garden the better you can bring it to perfection. In the  Languedoc region of France clients arranged for us to visit and revisit their home and extensive grounds until we knew everything about it, through all the seasons.  Fleeting visits are unlikely to reveal the full biodiversity spectrum.  These days such things as a biodiversity spectrum are treasured as they might not have been in the past.  A colony of frogs was an exciting discovery as Poppy took her sunset pictures, and was factored into the equation of how to restore an ancient pond.
