In a small garden or even on the balcony, espalier fruit is a good alternative. But trellis fruit must cut properly so that it can grow in a space-saving manner and also bear fruit.
Before you can trim the trellis at all, you have to create a climbing aid and tie the branches accordingly. Wires or other holding devices are ideal for this.
The branches must always be tied to this form framework, which is also called a trellis. Otherwise, the fine branches could break off under the weight of the fruit. Here you also have the opportunity to cut the tree correctly, so that classic shapes can emerge.
Cutting espalier fruit into certain shapes
If you want a columnar shape, for example, then the leading shoot must not be shortened, only the side branches must be trimmed regularly. Trellis fruit has to be trimmed relatively often so that it retains the desired shape. The shoots must not be cut off too far, otherwise they will not bear fruit.
