Hi, We have a lemon tree which is around 3 years old. Last year we had the first set of lemons which were like orange sizes. Now for the second time, the lemon tree has lots of lemons on it (each branch having 3 to 5 grouped) and from the last 3 weeks all the leaves are turning yellow and falling off. The tree is almost bald and has only lemons on it. Is our tree dying? Can anyone help? We have not put any fertilizers and we are watering the tree regularly. Vijaya
