trim leaders of green giants

9 years ago

I have a ton of green giants I have planted over the years. but some seem to be growing very tall but are remaining thin. I've heard that if I trim off part of the leader it will start to encourage bushier growth of the tree. In some cases its been kind of a problem. they grown so tall that a recent wind & rain storm unsettled them from the ground and have begun to tip, so I had to stake them off. they were planted about 3 years ago at 5-6ft and are now easily twice that size now. For privacy reason I would also like to "fatten" them up. No much use as a privacy screen if they just remain tall & skinny. Any thoughts? waste of time? thanks
