I have a Myrtus communis that is over 3 metre wide with a lovely dome shape. Unfortunately, it has split at a 'V' joint in the branches right in the centre of the shrub; without them, it will leave a large hole and lose half the shrub.
I will attempt to brace using a tree stake and cable the branches to stop them from splitting right apart. However, if I prune hard next spring in April/May to a bud just below the damage will a mature Myrtle regrow from old wood?
Many thanks
Phil
