Cactus, like people, can sunburn. But unlike people, the plant’s burn never goes away. It may seem odd that the heat-loving, desert-dwelling plants can be so sensitive, but that was just one of the tidbits of information offered Saturday during the weekly discussion at Green Things nursery’s winter horticulture series (AZ).
Well…. If it’s just a minor burn, the plant can heal over. Major burns can kill the plant, or cause permanent damage.
