Signs of Cold Stress in Dawn redwood
Symptoms
Dawn redwood tolerates cold well and flourishes when temperatures exceed 60℉. In winter, it needs to stay above 40℉. If temperatures drop below 20℉, while no immediate winter damage might be visible, branches can become brittle and dry by spring, preventing new growth.
Solutions
In spring, remove any dead branches that haven't produced new foliage.
Signs of Heat Stress in Dawn redwood
Symptoms
During summer, Dawn redwood should be maintained below 80℉. When temperatures surpass 95℉, the plant's leaves might lighten in hue, tips could dry and shrivel, and it becomes more prone to sun damage.
Solutions
Remove any sun-damaged and desiccated sections. Relocate the plant to a spot offering protection from intense midday and afternoon sun, or use a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
