Signs of High Temperatures in Valerian
Symptoms
In summer, Valerian should be maintained below 77℉. When temperatures surpass 86℉, the plant's leaves might lighten in hue, tend to curl, become prone to sun damage, and in severe instances, the whole plant could wilt and desiccate.
Solutions
Cut off 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 cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
