Signs of Cold Stress in Caucasian fir
Symptoms
Caucasian fir favors warmer conditions and cannot withstand low temperatures. It flourishes optimally when temperatures exceed 45℉. In winter, it must be maintained above 20℉. If the temperature drops below -10℉, foliage may lose some 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 the plant 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 air conditioning vents to prevent excessive air dryness.
Signs of Heat Stress in Caucasian fir
Symptoms
In summer, Caucasian fir should be maintained below 65℉. When temperatures surpass 75℉, the foliage lightens in color, and the plant becomes more prone to sunburn.
Solutions
Prune off any parts that are sunburned and desiccated. Relocate the plant to an area that offers protection from the midday and afternoon sun. Irrigate the plant in the morning and evening to maintain soil moisture.
