This post is about grafting Dragonfruit onto other cactus species and the benefits that this may provide. Even though Cacti have remarkable variation in appearence, they tend to have a high degree of graft compatibility within the family. I am wondering how we as fruit growers can use this to our advantage.
For example, maybe crest grafting to sturdy columnar cacti could create a permanent/inexpensive trellis that grew with the vine and never rotted? Or possibly some of the more drought tollerent species can be used as rootstocks in arid locations (such as Stenocerus pruinosus)? We might even find rootstocks that improve fruit size or quality.
I have successfully grafted dragonfruit to peruvian apple cactus (what species that is I will leave to the experts). I also have another graft on an unidentified semi-columnar cactus that is doing well. Opuntia (as suggested elsewhere on this forum) did not work for me, but that may just have been poor technique.
