beginners don`t sweat it it will come no need for redrilling new holes, that just stresses the trees and gives you less sap as the tree already has a hole to re-leave its self from. ive had a bucket test tap in since January and it hasn`t run a drop till a day ago. about 2 weeks ago i tapped my other bushes a they have run a few hundred gallons in the last 2 days its mother nature showing us who really controls what happens hang tight it will come and good luck
