Sunburn can cause brown spots and discoloration on the cactus, while temperature shock can lead to wilting and death. To avoid these problems, it is essential to provide the cactus with adequate shade and protection from extreme temperatures.

3. Detecting Pests and Diseases

Fairy Castle Cactus can also be affected by pests and diseases, such as mealybugs, scale, spider mites, and fungal infections. These problems can cause discoloration, wilting, and death.
