Question
I planted globe shrubs 3 years ago and have not pruned them yet.  Is there a guide to follow to make sure they are round?  Also, what about graphting Japanese red maple?  Taking branches off top and puting lower on the trunk?

Answer
Hello Rosalie

Pruning a plant to a specific shape can be difficult - but you may have a head start here.  Your Globe shrub is probably already roughly round.  Just clip around the sides and top of it a bit at a time and stop often to take a good look at what you've achieved.  

Remember - a bit at a time!  You can always cut off more if needs be, but you can't put it back on once it's off!!

Your Japanese Red Maple - I'm pretty sure it is not possible to take branches off the top and graft them lower down on the trunk, sorry.
