I'm new to having a ponytail palm, having received one as a Christmas gift this past year. It's been an indoor plant since that time, receiving mostly indirect light. I made the mistake of putting it outside in full sunlight for an afternoon. Some of the leaves now have some obvious sunburn damage. Other than this, have I caused irreparable damage to my plant? I've since brought it back inside but am upset at myself for not doing research before making such a drastic move.
