Signs of Heat Stress in Japanese tree lilac
Symptoms
Japanese tree lilac does not tolerate high temperatures well. When temperatures surpass 75℉, it might shed a considerable number of leaves, and in extreme cases, the entire plant could wilt and perish.
Solutions
Remove any sun-damaged and desiccated sections. Relocate the plant to an area 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.
