Pruning a Dogwood
We have an overgrown dogwood in the front of our garage. Great tree and it's in a perfect spot, but I really have to tame it. I hacked away at it last year, but each year it grows the 'broccoli heads' at the top while the rest of the tree is somewhat thin. How far down can I cut the branches and when is the best time to do so? Any suggestions on how to attack?
Thank you for your help.
