Misserfolge mit Rebenveredlungen, z.B. ihre angeblich kurze 

 Lebensdauer, hängen vielfach nur von fehlerhafter Behandlung bei 

 der Veredlung ab. Wichtig ist „besseres Schnittmaterial heranziehen, 

 bessere Veredlungen erzeugen und nur gänzlich einwandfreie Ver- 

 edlungen auspflanzen". Im Anschluss daran wird die Technik der
