Signs of Cold Stress in Southern red oak
Symptoms
Southern red oak tolerates cold well and flourishes when temperatures are above 60℉. In winter, it needs to stay above 50℉. If temperatures drop below 40℉, while no immediate changes might be seen in winter, branches can become brittle and dry by spring, with no new growth appearing.
Solutions
In spring, remove any dead branches that haven't produced new foliage.
Signs of Heat Stress in Southern red oak
Symptoms
During summer, Southern red oak should be maintained below 75℉. When temperatures surpass 85℉, 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 desiccated sections. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
