What should operators do during high temperatures to prevent plant damage?

The best course of action during high temperatures to prevent plant damage is to pause irrigation until the water cools. When temperatures soar, water drawn from the ground can become significantly warmer, which may negatively impact the plants if applied directly. Hot water can cause thermal stress to the roots and foliage, potentially leading to wilting or even plant death.

By pausing irrigation during peak heat and allowing time for the water to cool, operators can ensure that the plants are receiving water at a more optimal temperature. This practice helps in promoting better water uptake and minimizes the risk of thermal shock.

Adjusting watering frequency, checking filtration systems, or modifying pressure regulators may be important tasks in general irrigation maintenance, but they do not directly address the immediate need to ensure that the temperature of the water used for irrigation is suitable for the health of the plants during extreme heat conditions.
