🌡️ Heatwaves complicate watering as plants lose moisture quickly, soil dries, and roots struggle, according to France's ADEME. Morning watering, however, offers one advantage that evening watering does not: leaves and stems have time to dry during the day. Why morning watering can be safer than evening wateringWatering in the evening is often presented as the ideal solution because the soil remains cooler overnight. But early morning watering provides a useful margin of safety. Watering early in the morning, soaking the root zone deeply and keeping leaves as dry as possible can improve plant health while reducing waste.
