My driveway is lined with eight pin oaks . How hi can I trim them up from the bottom as they hang down pretty low.
Thank you

Greetings Don:
Two rules: never prune oak trees during the growing season; and never remove more than 50% of a tree's live crown. You will be fine if you adhere to those two rules :-)
