I watered my Spathiphyllum straight from the cold tap just because I was in a hurry: by that evening, with every leaf hanging to the floor, I understood what the water had blocked
A single watering with ice-cold tap water sent a healthy peace lily into complete collapse within hours—not from neglect, but from thermal shock that shut down the plant’s entire root system. The culprit? A temperature gap of just 20-30 degrees that disrupts cellular function before you even notice wilting.
