Orange tree leaves are completely gone!
I live in Florida and have a Valencia orange tree that is 3 or 4 years old. I have been taking care of this tree the best I can and it's been doing ok. Fertilized it about 3 times per year, the last time about 3 weeks ago. I did find an orange dog on it, so I have applied BT to it a couple times. Anyway, I noticed the other day it was losing its leaves really bad. I went outside and gave the tree a very light shake and all the leaves fell off. My tree is literally just sticks now. I also noticed the tree doesn't seem to be growing. It's the same size it was last fall. How tall should a 3-4 year old Valencia be? I'm so discouraged, can anyone help? I have no idea if it can be saved and what went wrong to cause it. See picture below.
