Cut back

As a rule, you do not have to cut back a spherical line. It is naturally poor in growth. It goes without saying that the crown can be thinned out, as the deciduous tree can withstand radical pruning. After severe storm damage, you should be careful to cut off kinked branches at the grafting points. Otherwise the spherical shape will be lost in the future.

Increase spherical line

The ball line is increased by grafting, a rather complicated process that is mostly reserved for specialists and tree nurseries.


The Phloespora leaf spot disease is a fungus that specifically targets the globular robin. You can recognize the infestation by small brown spots on the leaves. In this case, cut off any affected branches. Sometimes a radical cut is necessary for this.
