Tina, did you fertilize your
plant at the same time or soon after transplanting it? If so you may have burned out some of the roots. You may want to give the
plant a little bone meal to help the
plant re-develop more roots.
It may however be something as simple as the
plant might be sitting in the path of a heating vent, or a draft, both can do a number on the
plant.
Is there any pattern to the
plants leaves turning, is it happening from top to bottom, or maybe only on one side? Know that could help in determining the cause of the problem.
