Question
I have an apricot tree that has white spots on the back of the leaf along the lines that radiate from the center line.  It appears to move out from these lines to cover most of the back of the leaf.  The tree is outside and receives moderate sunlight and is about 15 - 20 feet tall. Any thoughts would be greatly appreciated.
Thanks.
Jim

Answer
Hi Jim, I know nothing about apricot trees here in FL but with citrus a white line going along the center line is too much water.  If not it could be missing minor nutrients so you could try epsom salts for a quick fix that should green it right up.  Hope that helps.  kathy
