Signs of Cold Stress in Rose-Painted Calathea
Symptoms
Rose-Painted Calathea favors warm conditions and cannot withstand cold. It flourishes optimally when temperatures exceed 65℉. In colder months, it needs to stay above 60℉. If the temperature drops below 50℉, foliage may lose its vibrant hue. Post-frost damage, the color progressively shifts to brown or black, accompanied by signs like wilting and drooping.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm setting for protection against cold. Position the plant near a south-facing window to ensure sufficient light exposure. Furthermore, avoid placing it near heating units or AC vents to prevent excessive air dryness.
