This fact is not good for either the vines or the olive groves.
The plants are in this moment in the most critical period: blooming. This a delicate moment for the plant because the rainfall and the jumps in temperature can create damage to the setting, in other words, the passage from pollinated flower to fruit.
Unfortunately, the weather is bizarre this year. We pass from 25° C. to 10° C., something anomalous for the period. But we cannot do anything concrete save for hoping that the plant reacts in the best of ways.
