My Opuntia Microdasys Albata has recently developed some orange/brown spots. The base is also covered in something like foil? Could anyone tell me if it is a disease, a sunburn or what? And what is that foil on the base? It looks like a snake that sheds his skin
Cactus stands in full sun for 7-9 hours a day. Besides that cactus looks healthy and okay, but I don't know what it is and I am concerned it might be some sort of fungus.
Thank you for answers!
