Cactus grafts are novelties formed by grafting scions with interesting shapes or colors on to an easy to root cactus rootstcock. Most of the colored scions do not produce chlorophyll and must be grafted to persist. These grafted cactus are most commonly done in Asia and imported into the USA.
The stem anatomy in cactus is different from most other dicots, so the scion and the rootstock must be aligned a little differently from other grafts. The central core of the scion and rootstock must be lined up to allow the vascular system to become connected.
Rootstocks are removed from stock plants, placed in a rooting substrate and cut to receive the scion.
The scion is held in place with ties, pins, glue, or specialized weighted clips.
Shade provides temperature control until plants have successfully grafted and rooted.
