Signs of Heat Stress in Swamp thistle
Symptoms
In summer, Swamp thistle should be kept below 75℉. When temperatures surpass 85℉, the plant's foliage might lighten, curl easily, suffer from sunburn, and in extreme cases, the whole plant could wilt and dry out.

Remove any parts that are sunburned and desiccated. Relocate the plant to a spot offering protection from the intense midday and afternoon sun, or use a shade fabric. Water the plant in the morning and evening to maintain soil moisture.
