Over 2 years ago we planted a gryselinia (sp?) hedge. To date I have
just left it alone (apart from watering & surface compost dressing).
All 16 plants look healthy, but they seem to be keeping themselves to
themselves - i.e. not actually forming a hedge!

The height of the plants varies between 2ft6 & 4ft (they were approx
1ft when planted) - anyone know if this is to be expected after 2+
years, or should they be taller?

More important, should I be doing anything more constructive?

TIA
