Signs of Cold Stress in Rosilla

Symptoms

Rosilla tolerates cold well and flourishes optimally when temperatures exceed 65℉. In winter, maintain temperatures above 55℉. If temperatures drop below 50℉, while no immediate winter changes may be apparent, reduced or absent sprouting could occur in spring.

In spring, remove any sections that have not sprouted.

Signs of Heat Stress in Rosilla

Symptoms

In summer, Rosilla should be kept below 75℉. When temperatures surpass 85℉, plant leaves may lighten, curl, become susceptible to sunburn, and in severe instances, the whole plant might wilt and dry out.

Solutions

Remove any sun-damaged and desiccated portions. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
