Signs of Cold Stress in Canyon ragweed
Symptoms
Canyon ragweed thrives in warmth and cannot withstand cold. Optimal growth occurs when temperatures exceed 60℉. In winter, maintain temperatures above 50℉. If temperatures drop below 40℉, foliage may lose color. Following frost, leaves progressively turn brown or black, and the plant may show signs of wilting and drooping.
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.
