What is the term used for the process of adding water to vines?

The correct term for the process of adding water to vines is irrigation. This practice is essential in viticulture, especially in regions with insufficient rainfall, as it helps to ensure that vines receive adequate moisture to grow properly and produce high-quality grapes. Irrigation can be managed in various ways, including drip systems, which deliver water directly to the roots, and furrow irrigation, where water is channeled through rows of vines.

In contrast, hydration generally refers to the process of ensuring that an organism has enough water, but it is not specifically used within the context of vine management in viticulture. Fertilization refers to the application of nutrients to enhance plant growth, which is different from the act of providing water. Watering, although perhaps related in casual terms, is not the precise technical terminology used in vineyard management practices. Therefore, irrigation stands out as the correct term for the intentional process of supplying water to vines.
