Signs of Cold Stress in Calla lily
Symptoms
Calla lily favors warm conditions and cannot withstand low temperatures. It flourishes optimally when temperatures exceed 60℉. In winter, it needs to be maintained above 50℉. If the temperature drops below 40℉, foliage may lose some color. Following frost damage, the hue progressively shifts to brown or black, and indications like wilting and drooping might appear.
Solutions
Remove any parts damaged by frost. Promptly relocate indoors to a warm setting for protection from cold. Select a location near a south-facing window for the plant, ensuring abundant sunlight. Furthermore, avoid positioning the plant near heating units or AC vents to prevent overly dry air.
