Signs of Cold Stress in Giant Coreopsis
Symptoms
Giant Coreopsis favors warm conditions and cannot withstand low temperatures. It flourishes best when temperatures exceed 60℉. In winter, it needs to be maintained above 50℉. If the temperature drops below 40℉, foliage may lose its vibrant color. Following frost damage, the hue progressively shifts to brown or black, and signs like wilting and drooping might appear.
Solutions
Remove any parts damaged by frost. Promptly relocate indoors to a warm setting for protection from cold. Select a location near a south-facing window for the plant, ensuring abundant sunlight. Furthermore, avoid positioning the plant near heating units or AC vents to prevent excessive air dryness.
