Signs of Heat Stress in Carolina hemlock
Symptoms
Carolina hemlock does not withstand elevated temperatures well. When temperatures surpass 70℉, it can suffer considerable leaf loss, and in extreme instances, the entire plant might wilt and perish.
Solutions
Cut off 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 for cover. Water the plant in the morning and evening to maintain soil moisture.
