Understanding the symptoms of stress is essential for proper care. Here are the most common signs that your prickly pear cactus may be under stress:

Causes of Stress in Prickly Pear Cacti

Several factors can contribute to stress in your cactus. Identifying the cause helps in choosing the right corrective action:
