Cutting depending on the variety
Depending on the variety, sour cherries develop different growth. While some develop whip-like long shoots and show an overhanging growth pattern, others show a short fruit wood and strive upright.
Varieties such as 'Gerema', 'Schattenmorelle' and 'Morellenfeuer' develop a strongly overhanging habit if they are not regularly restrained by a cut. Their whip-like shoots become extremely long and they fruit on the annual wood. With these varieties you have to shorten all long side shoots by two thirds. In addition, a clearing cut is advisable, in which old wood is cut out.
Varieties such as 'Ludwigs Früh', 'Dimitzer' and 'Schwäbische Weichsel' also grow overhanging. In contrast to the varieties already mentioned, their growth is weaker. They also need to be shortened considerably, albeit less.
Upright growing varieties
The following varieties develop a different habit: 'Saphir', 'Favorit', 'Heimanns Rubin Weichsel', 'Karneol', 'Koröser Weichsel' and 'Morina'. They grow upright, bear fruit on annual and old wood and do not bald. Here it is sufficient to remove or shorten the weak and inwardly growing shoots.

How to proceed:
