I planted a grapefruit tree two years ago and it hasn't done well.  No fruit has developed beyond a small ball that drops off.  There are not many new leaves.  The top branches are almost bare.  
Now that we are in the very hot weather the leaves do not look good.  Many are yellow,including the veins.  I water it according to the recommendations. I worry about overwatering it.  I did give it some fertilizer last month,I didn't see any change for the better or worse.
I would appreciate any advice you could give me.

Thank you,
Sally Hynes
