A little backstory, I have a Meyer Lemon tree that has very wilted and curled leaves. It only seems to be getting worse. I've tried adding lights but it only seems to dry out the leaves more. I received this tree about 2 weeks ago. The temperature outside was around 10F and it took 8 days to travel from California to Massachusetts. The tree looked a little wilted when I opened the box, but the next day the leaves started curling. Now nearly all leaves are curled like cigars. I am currently using a heating pad to heat the soil and have turned off the grow lights to try to prevent the leaves from drying more. Now, the question, Providing this works, how long will it take for the leaves to return to normal? If the leaves are a lost cause, how long before I notice any sort of growth? Here is what the plant looks like right now.
