The upper part of these trees is grafted with shoots from the same mother tree and thus produces exactly the same type of fruit. You can do the same with cacti.

More about grafting

Grafting is a technique used to join two plants together. It is mostly used to get identical fruit on different fruit trees. The top part of these trees are grafted with shoots of the same mother tree and therefore produce the exact same variety of fruits. The same can be done with cacti. When cacti are grafted, the bottom cactus will influence the flowering and growth time of the top cactus. Cacti from entirely different living environments (desert, snow or jungle) can be grafted together, resulting in a cactus of its own.

Martijn Baas

"What makes grafting cacti unique, is that you have them in the broadest variety of shapes and behaviours you can think of and are still able to join them."
With a background in Product Design, Martijn Baas has specialized in working with Mycelium, cultivating plants, Bonsai and a broad range of plant-shaping techniques. He also has a broad interest in topics like permaculture, analog electronics, game design and composing. He uses grafting as a way to play Dr. Frankenstein.
