I recently purchased the above named plant at my local Home Depot and after a couple weeks sitting outside on my patio, (I live in Arizona)some of the leaves, old and new, started curling up. Some of the curled up leaves have fallen off. I haven't overwatered, it gets plenty of sun. Temperature is perfect here, even at this time of year. What could be the problem?

Thanks in advance.

O believe it is being exposed to too cold conditions or it is sitting in waterr...make sure you take the foil off!
