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.
