Signs of Cold Temperatures in Annual ragweed
Symptoms
Annual ragweed tolerates cold well and flourishes optimally when temperatures exceed 60℉. In winter, it needs to stay above 50℉. If temperatures drop below 40℉, while winter changes might not be obvious, spring may see reduced or absent germination.
Solutions
In spring, remove any sections that did not germinate.
Signs of High Temperatures in Annual ragweed
Symptoms
In summer, Annual ragweed should be maintained below 75℉. When temperatures surpass 85℉, 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 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.
