Well I got a small Papaya tree. It was given to me, it is about 2 feet tall. I have been keeping it at the window. Lately I have been noticing the leaves are wilting. There is 2 things I can think of as why this is happening. I am thinking it is either too cold for the tree or it is not getting enough sun.
I am in Zone 9 so it is in the low 40s outdoors at night, but indoors it stays around 60-70s. It does not get much sun though. It only gets filtered sun and just barely. And lately it has been cloudy and dark too. It may not be any of these problems really so I am waiting on your opinions.
