Subject: Foliar Feeding of Apple trees

This morning my Friend Leemer applied a foliar fertilizer to his apple 
orchard.  He tried to direct the spray to the underside of the leaves.  
He and I had lunch and we learned it was going to rain tonight and 
tomorrow.  Leemer is worried because he feels the micronutrients will 
wash off the plants.  His question to me was, "How long does it take for 
the micronutrients to translocate through the leaf?"  

Can anyone shed some light on the subject?

Thanks
