Leaf drop from orange tree
1.5 metre high Orange tree in container (pit planted Jan. 1999) dropping leaves continuously with no apparent reason/visible damage. Leaves are pliable/healthy and smell of orange if rubbed but they are falling directly from the stem. Kept on enclosed, unheated porch year-round. Used an all-purpose pre-mixed liquid plant food for the first time in early May and the leaf drop started a week or so later. Flushed the container a few times since. Never had this problem before. Has never flowered but I don't mind. Could the roots be burned? Does it need repotting? Should I cut it back?

The feed was too strong and has caused the leaf drop as the roots could not take up water. Flusing with water was the right thing to do and it will probably recover.
