Signs of Cold Stress in Black gum
Symptoms
Black gum tolerates cold well and flourishes when temperatures are above 60℉. In winter, it needs to stay above 50℉. If the temperature drops 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 Black gum
Symptoms
In summer, Black gum should be maintained below 75℉. When temperatures go above 85℉, the plant's leaves might lighten in color, their tips could dry and shrivel, and the plant becomes more prone to sun damage.
Solutions
Remove any parts that are sunburned and dried. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
