Hi Damiano, grow a darli in Italy is possible but could be a very very hard challenge (i live close to Modena, so a little bit hotter than Trentino). Podunk gave you very helpful advices! next time keep the plant outside in a shaded but luminous place, don't use ice (o siberini come nella foto, anch'io persi la mia prima darli cosi'): you will be forced to change them too often, they like cool substrate but don't like when temperature jumps up and down
