Signs of Heat Stress in Fernleaf phacelia
Symptoms
During summer, Fernleaf phacelia should be maintained below 75℉. When temperatures surpass 85℉, the plant's leaves might lighten, curl easily, become prone to sunburn, and in severe instances, the entire plant could wilt and dry out.
Solutions
Remove any parts that are sunburned and dried. 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.
