Signs of Cold Stress in Rainbow tree
Symptoms
Rainbow tree favors warm conditions and cannot withstand cold. It flourishes best when temperatures are above 65℉. In winter, it needs to be maintained above 60℉. If the temperature drops below 50℉, its leaves might lose some color. Following frost damage, the color progressively shifts to brown or black, and signs like wilting and drooping may appear.
Solutions
Remove the parts affected by frost. Promptly relocate the plant indoors to a warm setting for protection from cold. Select a location near a south-facing window for the plant, ensuring plenty of sunlight. Furthermore, avoid positioning the plant near heating units or AC vents to prevent excessive air dryness.
