Plants usually used to make hedges are shrubs, consequently agronomic works to be carried out are the same as the above. Pruning has to be made when new vegetation reaches dimensions hiding the regular shape given at the beginning ; in case the hedge is square and linear, branches extending beyond the edge give a feeling of disorder and neglect. The first pruning has to be made in spring / summer time, say after the greatest growth once the vegetation has been restarting, while last pruning has to be made almost at the end of plant’s vegetative period so that the hedge keeps its tidy shape during the whole autumn and winter time.
