Hey all! I'm having a problem with my aloe plant. I'm unsure of the exact variety, but it has been called a tree aloe by several people. I bought it when it was about a foot tall 4 years ago, and it has grown to 3-4 feet, and has sprouted over 50 offshoots, some of which I left attached. It has started to get brown areas on the many of the leaves and it has crept up the plant and now the new leaves are almost affected! The brown areas are are not soft, it's kind of like a dark hardness that covers the leaf. I've never seen this on an aloe before. I love this plant. Help!
