Loph – do you degraft? If so why and when?

I have a bunch of loph. About 50 caespitosa seedlings that look like fat pea's. 5 small/medium size adult caespitosa, and a few grafts on PC pach that i made from cutting small heads off the adults.

Some grafts are newer but some are slightly older and making good progress. Think the largest is about 7 months old and started out as pea sized.

Do you guys degraft? If so, what initiates your decision to do this?

I have degrafted in the past and one of my mid-sized adults is from a degrafted plant, but I cant remember why I did it. But its definitely very healthy still.

I have also taken a loph grafted to selenecerius, cut it about 1/4" below the graft, let it heal and the just buried the whole thing so the seleneceruis section became the new loph roots.

But im curious to hear everyone's thoughts and preferences about degraft of loph. Im in no rush and they are not really large or anything. But should the time come id like to know if I should watch out for a "trigger event" to run and get a knife.
