Taming Hazel after hard cut back
I have a neighbour who has hazels in their boundary. They have been getting more and more tree like. They recently hacked them back to about 3 or 4ft, the limbs are quite large. They look slightly ugly at this point.
The gardens are narrow. I'm assuming the hazel will spring back next year.
What would be the best approach to stopping them flopping out at the sides?
Should they clean the cuts, and leave taller stumps, or take them to the ground?
They are already multi-stemmed, which might be natural, but I guess there is a slight fear that new growth will occur at the boundary of the existing stumps.
Oh and have they picked a bad time of the year?
