Signs of Cold Stress in Boston fern
Symptoms
Boston fern favors warm conditions and cannot withstand low temperatures. It flourishes optimally when temperatures exceed 65℉. In winter, maintain temperatures above 55℉. If the temperature drops below 45℉, foliage may lose vibrancy. Following frost exposure, leaves progressively turn brown or black, exhibiting signs like wilting and drooping.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm setting for protection from cold. Position the plant near a south-facing window to ensure sufficient light. Furthermore, avoid placing it near heating units or AC vents to prevent excessive air dryness.
