Signs of Heat Stress in Butterfly weed
Symptoms
During summer, Butterfly weed should be maintained below 85℉. When temperatures surpass 90℉, the plant's foliage might lighten, curl, become prone to sunburn, and in extreme cases, the whole plant could wilt and dry out.
Solutions
Remove any sun-damaged and desiccated portions. 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.
