Ideal Temperature for Rock tobacco
Signs of Cold Stress in Rock tobacco
Symptoms
Rock tobacco favors warm conditions and struggles with low temperatures. It flourishes optimally when temperatures exceed 65℉. In winter, it needs to be maintained above 60℉. If the temperature drops below 50℉, its leaves might lose some color. Following frost damage, the foliage progressively darkens to brown or black, and signs like wilting and drooping can appear.
Solutions
Remove any frost-damaged sections. Promptly relocate the plant indoors to a warm setting for protection from cold. Position the plant near a south-facing window to ensure sufficient light. Furthermore, avoid placing it near heating units or AC vents to prevent overly dry air.

In summer, Rock tobacco should be kept below 75℉. When temperatures surpass 80℉, the leaves' color fades, and the plant becomes more prone to sunburn.
Solutions
Prune off any sun-scorched and desiccated portions. Relocate the plant to an area offering protection from the intense midday and afternoon sun. Water the plant during the morning and evening to maintain soil moisture.
