Phil Latzman/KJZZ KImberlie McCue, of the Desert Botanical Garden, and Adam Vickers, also known as the "Cactus Doctor." The Arizona man known as the "Cactus Doctor" has seen a lot of sick patients lately. “It’s heartbreaking. We’ve never seen this. It’s a phenomenon that we’ve never seen — and it’s devastating," said Arizona native Adam Vickers. Vickers has his own landscaping company specializing in their care. And lately, they have needed a whole lot of care, especially the iconic saguaro. “We’re seeing the saguaros shrivel up, and actually the soil is heating up as well, and it’s causing rotting on the base of the saguaro and the flesh begins to deteriorate and turn in to bacteria,” Vickers said.
