If a grafted cacti falls off will it grow roots?

[keithp2012]

I've got a grafted gymno that is purple and gets random purple or pink offsets. When it does outgrow its graft and falls off will it grow roots and survive on its own in a pot? How do you care for them during this vulnerable time?

If it has chlorophyll it will probably survive, if it's one of the pink, red or yellow ones it will die. I believe the purple has chlorophyll, so give it a try.

Do I just set it on the soil and water, how do I stimulate it to grow roots?

I personally like to grow all of my cacti on their own roots, so I de-graft such plants (in the warm weather growing season if possible) and treat them as cuttings as I did with these Discocactus horstii:


Grafted plant primary offset removed using a sterilized
exacto knife to produce minimal cut surface - put aside to callous.


Cut surfaces satisfactorily healed.


In 2¾" square plastic pots - resting on surface of my standard
soilless mix (barely moistened) with desert grit top dressing.
I keep soil barely moist until roots form
