Talk about how much sun it gets and what size/kind of pot it's in please. Quite possibly it wants more water seasonally. If it gets a lot of sun (which it likes) you are
growing it "hard." This approximates its natural
growing conditions in the Canary Islands. Plants in nature are rarely, if ever, perfect. Brown leaf tips (just the tips) happen in most aloe species and don't mean a whole lot in a larger plant/clump of plants that are healthy and
growing. Does it
flower? How humid is your area of Texas?
