Signs of Cold Stress in Rambutan
Symptoms
Rambutan favors warm conditions and cannot withstand cold. It flourishes optimally when temperatures exceed 77℉. In winter, maintain temperatures above 68℉. If the temperature drops below 59℉, 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 setting for protection against 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.
