Signs of Cold Stress in Norway spruce
Symptoms
Norway spruce exhibits exceptional cold hardiness, but winter temperatures should remain above -22℉. Should the temperature fall below this point, while no immediate changes might be apparent in winter, branches could become fragile and desiccated by spring, with no new growth appearing.
Solutions
During spring, remove any lifeless branches that have not developed fresh foliage.
Signs of Heat Stress in Norway spruce
Symptoms
Norway spruce does not tolerate elevated temperatures well. When temperatures surpass 68℉, it might shed a considerable number of leaves, and in extreme instances, the entire plant could wilt and perish.
Solutions
Cut off the sun-damaged and dried-out sections. Relocate the plant to an area offering protection from the midday and afternoon sun, or employ a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
