Signs of Cold Stress in KÅwhai
Symptoms
KÅwhai favors warm conditions and cannot withstand cold. It flourishes optimally when temperatures exceed 65℉. In winter, it needs to be maintained above 50℉. If the temperature drops below 35℉, foliage may lose its vibrant color. Following frost exposure, leaves progressively turn brown or black, and signs like wilting and drooping might appear.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm area 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.
