Signs of Cold Stress in Horseweed
Symptoms
Horseweed tolerates cold well and flourishes optimally when temperatures exceed 60℉. In winter, maintain temperatures above 50℉. If temperatures drop below 32℉, while winter changes might be unnoticeable, spring may see reduced or absent sprouting.
Solutions
In spring, remove any sections that have not sprouted.
Signs of Heat Stress in Horseweed
Symptoms
During summer, Horseweed should be maintained below 75℉. When temperatures surpass 90℉, the plant's leaves might lighten, curl, become prone to sunburn, and in severe instances, the whole plant could wilt and dry out.
Solutions
Remove any sun-damaged and desiccated portions. Relocate the plant to a spot offering midday and afternoon shade, or use a shade cloth. Water the plant in the morning and evening to keep the soil hydrated.
