I have a young, indoor, variegated lemon tree that I purchased in November 2020. This is my first tree and I live in PA. I understand that the climate here is not optimal for this type of tree. Leaf drop in winter is understandable but my new tree is dropping healthy looking leaves constantly. The roots are growing like crazy however. My tree is in full Eastern sunlight and the sits in a window where I can close the curtains at night to provide more warmth in the winter. I admit that I have over-watered this tree out of concern for it’s well being.
Would anyone have suggestions to care for this tree? I find it very odd to have excessive root growth AND excessive leaf drop. I’m thinking it could be due to the soil I used to repot the tree. Please respond if you have any thoughts. Thank you :)
