I am currently growing a lleylandii hedge (which I intend to control with
vigour!), but - the plants having reached a height of about 4 1/2 foot, two
of them have snapped at the trunk, leaving 3 foot high plants. I assume
that the trunk will not grow anymore, but should I pull the 2 plants out and
start again, or is there anything I can do to make them grow upwards? Or
should I just leave them and hope the rest of the plants will fill the gaps
in? (the broken plants aren't adjacent).

The hedge is planted at 2 foot intervals, and I planted them about 2 months
ago.

Thanks for any help
