Cherry blossoms: Answer: cherry

Dear Sonia,
in general cherry trees tend not to be self-fertile, meaning that, although their flowers have both male and female sexual organs, flowers tend to be pollinated better by pollen from another cherry. For this reason, often self-fertile varieties are chosen (you need to ask at the time of purchase) or at least two neighboring cherry trees of different varieties are planted; in this way it is easier for most flowers to be pollinated, but it is also sufficient for a neighbor to have a cherry tree in the garden. In addition to this, it can happen that a sudden change of climate at the time of flowering causes premature drying of the flowers, which therefore cannot be pollinated. I believe your cherry is grown in pots (to be able to put it in a greenhouse), so the variables increase. Usually the cherry trees are grown in the open ground, and they bloom when the nocturnal lows naturally tend to rise, when spring arrives; the Italian spring season is characterized by mild temperatures and good humidity, due to rainfall. So a cherry grown in the open ground will flourish at the perfect moment, with a climate suitable for flower development, and with spring rains coming. A tree kept in a greenhouse can bloom prematurely; if it is moved outdoors in a rash way it can lose all the flowers due to the cold, or due to the lack of watering in the vase. If then the tree was kept in a greenhouse pot throughout the winter, and then it was buried in early spring, then it may also be that the flowers have fallen due to transplant stress; not knowing how things went, it is difficult to understand what the problem is, given that flowering requires great energy from plants, and the right climate; if the plant suffers stress of any kind, it generally tends to lose the flowers, or even the fruits already attached, to avoid having to use energy in an activity destined to fail.
