Signs of Cold Stress in Norfolk island pine
Symptoms
Norfolk island pine favors warmer conditions and cannot withstand low temperatures. It flourishes optimally when temperatures exceed 65℉. In winter, it needs to be maintained above 45℉. If the temperature drops below 32℉, its foliage might lose some color. Following frost exposure, 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 setting for protection against cold. Position the plant near a south-facing window to ensure sufficient light. Furthermore, avoid placing it close to heating units or AC vents to prevent the air from becoming too dry.

In summer, Norfolk island pine should be kept below 75℉. When temperatures rise above 85℉, the leaves' color fades, and the plant becomes more prone to sun damage.
Solutions
Prune off any sun-scorched and desiccated sections. Relocate the plant to an area that offers protection from the intense midday and afternoon sun. Water the plant during the morning and evening to maintain soil moisture.
