Experts advise strategic plant watering during extreme heatwaves, emphasizing timing is as crucial as quantity. Simply watering more isn’t the solution; the optimal time minimizes water loss through evaporation. Recommendations center around watering during the coolest hours of the day, typically early morning or late evening. This approach allows plants to absorb moisture before intense sunlight and high temperatures take effect. The guidance aims to maximize hydration and improve plant survival rates amidst prolonged heat. Ignoring optimal timing can render watering efforts ineffective, potentially leading to plant stress and damage.
