Slide your hand between your alocasia and the window glass after dark and hold it there: it’s the test growers do before blaming anything else
Experienced growers perform a simple test before adjusting watering or fertilizer: they slide a hand between an alocasia’s leaves and the window glass after dark to detect hidden cold pockets. Window glass can drop 15–20°F below room temperature, mimicking nearly every other houseplant problem. This diagnostic shortcut reveals whether temperature stress is the real culprit.
