Signs of Cold Stress in Japanese larch
Symptoms
Japanese larch favors warmer conditions and cannot withstand cold. It flourishes best when temperatures exceed 50℉. In winter, it needs to be maintained above 32℉. If the temperature drops below 14℉, its foliage might lose some color. Following frost damage, the leaves progressively turn brown or black, and signs like wilting and drooping can appear.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm area for protection from the cold. Select a location near a south-facing window for the plant, ensuring plenty of sunlight. Furthermore, avoid positioning the plant near heating units or air conditioning vents to prevent overly dry air.

In summer, Japanese larch should be kept below 68℉. When temperatures go above 77℉, the leaf color fades, and the plant becomes more prone to sun damage.
Solutions
Cut off any parts that are sunburned and dried out. Move the plant to a spot that offers protection from the midday and afternoon sun. Water the plant in the morning and evening to maintain soil moisture.
