Signs of Cold Stress in Painted-leaf begonia
Symptoms
Painted-leaf begonia favors warm conditions and cannot withstand cold. It flourishes optimally when temperatures exceed 65℉. In winter, it needs to be maintained above 60℉. If the temperature drops below 41℉, foliage may lose its vibrant hue. Following frost damage, the leaves progressively turn brown or black, and signs like wilting and drooping might appear.
Solutions
Remove any parts affected 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 close to heating units or AC vents to prevent excessive air dryness.
