Q.Indoor lemon tree
My lemon tree dropped all of its leaves recently and it looks like it is dying. I have had the tree for a couple of years and it has produced 8 large lemons, with new white flowers but no further lemons. It sits on my south-facing window sill and the temperature has been cold in recent weeks (we live in Glasgow) and I’m wondering now if the tree has died or is suffering from cold damage or I am over watering it. I recently used winter feed to see if this would help but it seems to have made it worse. What can I do to save my tree? Thank you.
It is normal for your Lemon Tree to drop some leaves in the winter and early spring, loss of all of it's leaves could be due to several issues.
Temperature, improper care, fungus, insects, and excess fertilizer.
Here are some articles to help you determine the cause and to correct the care you are giving your tree.
