ring high 5-10 cm, so to generate a water reserve when irrigating. It is crucial to assess also the soil
typology (clay versus sandy), which determines the capacity to hold water.
Weeding
In certain circumstances, with the aim to oppose water lack (especially during dry periods and/or
in presence of clay and compact soils), it can be useful to effectuate soil weeding, which means to
liven up and to crumble the superficial soil layers. This practice avoids the detailed water reclimbing
and increases the soil softness, with many benefits such as improving roots development, gas
exchange between soil and atmosphere and growth of edaphic microorganisms.
Support system
After laying the support pole (cf 2.2.4), and depending on species growth, it is necessary to verify
periodically the joining ring (preferably in vegetal fibre) to avoid constriction events.
Superficial soil processing
For species less competitive and long growing, it is a good practice to reduce competition with
other species trough the periodical cleanliness of the surrounding ground. In presence of clay soil, it is
also opportune to hoe periodically the superficial layers (above primary roots).
Plants replacement
In the event of an high percentage of desiccation of planted individuals, it is deserve to replace
them, if necessary with more suitable species. Before the plants replacement it is necessary to identify
the cause of desiccation.
Anyway, it is common that a small percentage of plants does not root. However if all procedures
necessary for a successful implantation are correctly realized (cfr. 2.1, 2.2., 2.3), number of lost plants
will be negligible (and so easily replace).
Manuring
When the forestry intervention has been realized in a degraded area (cf. 1.2) characterized by very
altered soils, it could be necessary to add additional manures, apart of those added before bedding out.
However, manuring is not provided in protected areas, where it is never realized.
Weed growing limiting
In particular, apart of above-mentioned mulching, it should be necessary to realize some weeding
interventions (manual or mechanic), paying attention not to damage new plants (especially close to
root collar).
Formation pruning
During first years, especially for fast growing trees, it is necessary an accurate control of their
stability, in order to intervene with appropriate pruning, if necessary. For species susceptible to
pruning, this intervention should be always realized so as to avoid fungal infections or other parasitic
diseases. To facilitate a fast growing of trunk, for some species it would be necessary also to remove
suckers.
