This is obteined by using only organic insecticides and fungicides ,with low toxicity and high selectivity and only when is required because of significant pest and disease activity. Thus no preventive treatments is done and scouting must be done constantly.
The specific knowledge of parasites is foundamental.
Organic ferilizers on plants avoid uncontrolled growth determing only a steady development and so more resistence and longevity. This kind of management leads to an environment where beneficials are able to contain parasites and help plants in adsorbing nutrients from soil. At the base is as well to plan the garden in the way that everything is at his place…in right light and shade, in right soil conditions.
All of this makes your garden, aside from beatiful, an healthy place where enjoy your time.
