Signs of Cold Stress in Japanese meadowsweet
Symptoms
Japanese meadowsweet tolerates cold well and grows optimally when temperatures exceed 65℉. In winter, it needs to stay above 55℉. If temperatures drop below 40℉, while no immediate winter damage may be apparent, 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 Japanese meadowsweet
Symptoms
In summer, Japanese meadowsweet should be kept below 75℉. When temperatures rise above 85℉, the plant's leaves might lighten in hue, their tips could dry and shrivel, and the plant becomes more prone to sunburn.
Solutions
Remove any sun-damaged and desiccated sections. Relocate the plant to a spot offering protection from the midday and afternoon sun, or use a shade cloth. Water the plant in the morning and evening to maintain soil moisture.
