Signs of Cold Stress in Japanese callicarpa
Symptoms
Japanese callicarpa tolerates cold well and flourishes optimally when temperatures exceed 60℉. In winter, it needs to stay above 50℉. If temperatures drop below 40℉, while no immediate winter damage might be apparent, branches can become brittle and dry in spring, preventing new growth.
Solutions
In spring, remove any dead branches that haven't produced new foliage.
Signs of Heat Stress in Japanese callicarpa
Symptoms
In summer, Japanese callicarpa should be maintained below 75℉. When temperatures surpass 85℉, 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 fabric. Irrigate the plant in the morning and evening to maintain soil moisture.
