How tall do hedges grow if they are not cut?

Question

My neighbours hedge is out of control, it hasnt been cut for years, now it looks like its turned into a row of trees and is flowering at the top. its already around 18 feet tall,

How tall will the hedge grow ?

Answer 1

wow 18 feet already? yeah they are now Trees, some hedges can grow into trees, and how tall would depend on the type of tree it is.

Answer 2

depends on the variety really.  If it is invading your yard or unsitely and you live in city limits you may want to play that card. Maybe offer to trim them for your neighbor they may not be able to do it anymore.

Answer 3

very tall

Answer 4

They will grow as large as trees if they are not kept cut. Ask your neighbor if they need help with getting them cut. Then offer to do it for them, or find them a person to cut them.

Answer 9

Depends on the plant species.  Ligustrum can get to 15 feet, siberian elm to 30 feet, I don't know about boxwood...I'm guessing 12-15 feet and hollies........well, they are truly trees to start.  

Depending on the species you can cut them back to the ground or you must leave a couple of inches stem.  Last fall we cut back a siberian elm hedge that got to 12 feet tall.  We took it to the ground and now, in July, it is up to four feet.  It should have been cut back several times this year to make a denser hedge but this was an experiment.

Aside from being lazy, could be the neighbor wants a higher privacy screen.
