Can I degraft this?

[Shane]

I've never done a degraft before but I'd like to degraft this Mammillaria I bought. Is it possible or would the cut be too big and dry the plant out? I was planning on just slicing it (then letting it callous)

Sure, you can do this. Just make a cut close to the grafting surface and then remove the remaining stock parts, do a second cut deeper if needed. That Mammillaria is big enough to root in coming weeks or months successfully.

Did you buy these from a Polish seller? The Myrtillocactus stock looks familiar. Before slicing, give it a light tug just to see if it might pull off without damage. Before I slice my degrafts, I often check if it can be simply twisted off from the rootstock. Sometimes this lets you save a step in waiting for surfaces to dry, potentially applying antifungals, and applying rooting hormones.

Thanks for the advice, 7george and Pereskiopsisdotcom!

Yes I did in fact. I thought I was buying a normal M. longimamma, and being inexperienced thought that was what was pictured. I'm not sure quite what this is. The seller called it monstrose, but I think it's maybe a hybrid. Pretty cool whatever it is. I don't regret mistakenly buying it. As a side note, I did later buy a nice longimamma for $3 in the LA flower district
