I don't wait that long - usually. I don't think it is necessary, few days should be plenty. If I get 'lazy' or too busy to attend the plants, they will wait longer...I tend to be more attentive with thicker trunks :) - I let them callus for just few days.

Nice Jade! I recently got the same type myself. I agree with Rina's comments, a few days or a week should do.

Here in Reno with echeverias the ends callous in a couple of hours but I'll give the crassula a few days.

OT-C. campfire is the worst mealy magnet I've ever had.

Agree with the above, I have found variegated morphs take longer to root and in my experience the single leaves come back non variegated.

Mark are you saying the cuttings revert to all green?
