Signs of Cold Stress in Oriental arborvitae
Symptoms
Oriental arborvitae tolerates cold well and flourishes optimally when temperatures exceed 59℉. In winter, it needs to be maintained above 41℉. If temperatures drop below 32℉, while winter might show no immediate effects, branches can become brittle and desiccated by spring, with no new growth appearing.
Solutions
In spring, remove any dead branches that have not produced new foliage.
Signs of Heat Stress in Oriental arborvitae
Symptoms
In summer, Oriental arborvitae should be kept below 77℉. When temperatures surpass 86℉, the plant's leaves might lighten in hue, their tips could dry and shrivel, and the plant becomes more prone to sun damage.
Solutions
Remove any sun-damaged and dried sections. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade fabric to provide cover. Water the plant in the morning and evening to maintain soil moisture.
