What Is Succulent Sunburn?
Succulents are sunlight-loving plants that require about 2 to 3 hours of sunlight to thrive. But, if they get exposed to long hours of direct sunlight, they will experience sunburn. The temperature range at which succulents typically grow is from 60 to 90 degrees F. When both indoor and outdoor plants get overly exposed to sunlight, their leaves can get a sunburn.
Overexposure of succulents to sunlight causes succulent sunburn and in the process, the plant’s leaves develop irreversible blackish, brown or dark red patches. But succulents that are exposed to the right amount of light will begin developing blushing, which is a beautiful coloration. Succulent sunburn happens when leaf tissues burn after being exposed to UV rays or high-intensity light. So, do not give your succulents a sunbath by letting them stay for too long in sunlight.
