Signs of Cold Stress in Orange spruce
Symptoms
Orange spruce exhibits exceptional cold hardiness, yet winter temperatures should remain above -4℉. Should the temperature fall below this point, while no immediate changes might be apparent in winter, branches could become fragile and parched 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 Orange spruce
Symptoms
Orange spruce does not tolerate elevated temperatures well. When the temperature surpasses 68℉, it might experience considerable leaf shedding, and in extreme instances, the entire plant could wilt and perish.
Solutions
Remove the sun-damaged and desiccated sections. Relocate the plant to an area offering protection from the midday and afternoon sun, or employ a shade cloth to provide cover. Water the plant in the morning and evening to maintain soil moisture.
