Hornbeam hedges are very popular because they are so vigorous and form a dense hedge within a few years. However, the abundant growth also has a downside: you have to cut back a hornbeam hedge more frequently at first, and later at least twice a year.

This is how strong the growth of the hornbeam hedge is per year
A hornbeam grows a little more slowly in the first few years after planting until it gets used to the location.
But then she really gets going. The growth is between 30 and 40 centimeters per year, both in height and in width.
If you do not cut the hornbeam hedge regularly, it will easily grow three to four meters high and several meters wide. However, it bares from below, since the lower shoots hardly branch out without a cut.

Beech hedges grow even faster than hornbeam hedges. Their growth per year is about 50 centimeters in height and width.
