S4.1 The Root System
root system - root protection - bare root shrubs (bagged) - rootball shrubs - container grown shrubs - cell grown shrubs
The Root system must be well developed by good nursery practice influenced by the natural characteristics of the species/cultivar taking into account its age and growth rates under the cultural and growing medium within which it is growing. The system must not show any coiled main roots close to the collar, nor any physiological damage.
The root system must not be allowed to dry out at any time.
