When I start my take off with a tail dragger I hold full up elevator. Once I get up a little speed then it is back to neutral. Then as the plane is starting to lift I give a little up elevator.

You need to check on your prop clearance. If you need more then get some bigger diameter wheels. You also could be using too long of a prop. Or maybe you just need more practice. Also is your plane balanced correctly? Don't get discouraged.
