The question of irrigating citrus trees during winter is one of the most frequently asked by farmers, especially in regions with irregular rainfall. Scientifically, citrus trees enter a new growth cycle in autumn and early winter, which means their water requirements remain significant during this period.
If rainfall is insufficient, irrigation becomes necessary to support the tree’s vital processes, particularly root growth and the formation of flower buds that will bloom in the next growth season. A lack of water during this stage can have clear negative effects, first affecting the fruits, followed by the leaves and branches, with the feeder roots being impacted first.
Insufficient irrigation during fruit development can lead to smaller fruit size, reduced juice content, and lower overall quality. Therefore, it is recommended to monitor soil moisture and implement a balanced irrigation schedule that aligns with the amount of rainfall received.
