Signs of Heat Stress in Red columbine
Symptoms
During summer, Red columbine should be maintained below 75℉. When temperatures surpass 85℉, the plant's foliage might lighten, curl, become prone to sun damage, and in severe instances, the whole plant could wilt and desiccate.
Solutions
Remove any sun-damaged and dried portions. 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.
