We are planning putting in a privet hedge along one edge of our
property. At the present time, there is a four foot high chain link
fence installed by my neighbor. We want to put the hedge in for
privacy and safety (neighbors have 3 large dogs who can, and do, jump
the fence).

I know to place the individual plants one to two feet apart, but how
far from the fence must I be in order for them to not grow into the
next yard?

I hope I asked the question correctly, I'm far from being a gardener.

TIA
