Once they are planted, the trees grow naturally. Before that, in order to ensure their quality, they go through a selection process. First, they go through an insertion phase, in which ramifications of mother trees are transplanted into the new tree to guarantee the quality is maintained. Then, the trees undergo observation during 3 weeks and are treated with organic fertilizer, to assure their growth. After being stabilized, they are then planted and left to grow on their own.
