Signs of Cold Stress in Japanese angelica tree
Symptoms
Japanese angelica tree exhibits moderate resilience to cold and flourishes optimally within a temperature range of 60℉ to 75℉. In winter, temperatures should not drop below 50℉. If the temperature drops below 40℉, foliage may darken. In extreme instances, water-soaked tissue death, wilting, and drooping can occur, with leaves progressively turning brown.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm setting or construct a temporary greenhouse for cold defense. When bringing the plant inside, select a spot near a south-facing window to guarantee sufficient light. If natural light is inadequate, consider using artificial grow lights.

In the summer, Japanese angelica tree should be maintained below 75℉. When temperatures surpass 85℉, the plant's development slows, its leaf color fades, and it becomes more prone to sun damage.
Solutions
Prune off any sun-scorched and desiccated sections. Relocate the plant to an area offering protection from the afternoon sun. Irrigate the plant in the morning and evening to maintain soil moisture.
