Etages Espalier trees on levels

Espalier trees with tiers or frames are a classic application that is chosen on the one hand for structure in the garden and on the other hand for a structured green buffer. This form was mainly used for fruit cultivation. The tiered form was also used as an ornamental tree or for privacy purposes, but this has been abandoned. The frames have a distance of 30cm between them for most trees, but large-leaved trees can also be planted to 40cm.
Evergreen trees are less suitable for multi-storey maintenance.
