Signs of Heat Stress in California poppy
Symptoms
During summer, California poppy should be kept below 75℉. When temperatures surpass 85℉, the plant's foliage might lighten, curl, become prone to sunburn, and in severe instances, the entire plant could wilt and desiccate.
Solutions
Remove any sun-damaged and dried-out portions. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade fabric. Water the plant in the morning and evening to maintain soil moisture.
