I have a large Ponytail Palm (not a palm I realize) in a pot on the porch. The pot is rusty and must be replaced. I couldn't bring it inside so I thought I would test its limits. I didn't think to at least cover it. Well 24 f is apparently a bit less than it likes, at least in a pot on an open unscreened porch. The top is getting white. Does anyone have experience with Ponytails to know if it will grow back? The same plant lost a lot of leaves when I tried to make it an indoor plant. It needs sunlight. But this time its turning white from the top rather than brown from the tips.
