Root pruning. Get a spade. A good one. Buy a fine-grain flat file to keep
the spade sharp. Drive it straight down in a circle around each plant. The
circle should be about half the diameter of the widest circle of branches.
Go straight down ONLY - do not lift as if you were trying to remove the
plant. Just STRAIGHT DOWN. If you feel no resistance, make the circle a bit
closer. Do this one in early spring and again in the late fall.

The tar idea is stupid. Who told you that?

Does anyone know of any good methods for slowing down an "aggressive"
hedge?

Actually, this isn't any "ordinary" hedge as since it's been cut back
I've noticed it has some huge, "raw"-looking branches.

I've heard you can put tar on the branches and that'll stop 'em from
growing.

Anyone?

Thanks!
