SHRUBS
As to the description of agronomic works to be carried out it is suitable to follow the same rules as for the big trees with just a few changes: it is not necessary to form a small round for each shrubs (unless in case of solitary shrubs). As far as the vegetative shrub bushes are concerned it is more suitable to make hoeing weeding to ventilate the upper surface of the soil and to keep the ground free from weeds. To this purpose it can be suitable to use mulch materials (for instance chopped pine bark, volcanic lapillus and /or fabrics) that spread over the previously weeded flowerbeds, limit the growth of weeds. Manure’s quantity required for each shrubs is of about 40/60 gr.
