Signs of Cold Stress in Japanese wisteria
Symptoms
Japanese wisteria tolerates cold well and flourishes best when temperatures are above 59℉. In winter, it should be maintained above 41℉. If temperatures drop below 32℉, while no immediate winter changes might be apparent, branches can become fragile and dry in spring, with no new growth appearing.
Solutions
In spring, remove any dead branches that have not produced new foliage.
Signs of Heat Stress in Japanese wisteria
Symptoms
During summer, Japanese wisteria should be kept below 77℉. When temperatures surpass 86℉, the plant's leaves might lighten in hue, tips may dry and shrivel, and the plant becomes more prone to sun damage.
Solutions
Remove any sun-damaged and desiccated sections. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade fabric. Water the plant in the morning and evening to maintain soil moisture.
