Symptoms

Signs of Heat Stress in Prairie dock

Symptoms

In summer, Prairie dock should be maintained below 75℉. When temperatures surpass 85℉, the plant's leaves may lighten in color, tend to curl, become prone to sunburn, and in severe instances, the entire plant might wilt and dry out.

Solutions

Remove any parts that are sunburned and dried. 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.
