i have propaged an enormous amount of jades from a few tiny cuttings.
this one i took in 2006 (so 15 years now): tiny 3" 1 stem:
i experimented with new method similar to air-layering: found some pics in asia for adeniums..so decided to try on my jades: wrapped moist paper and then saran wrap over the trunk not tightly and remoistened now and then for about 1 month: got roots inside the paper!
so i cut it off , stuck it into plastic tube positioned over moist coco-chips to maintain high humidity and keep the bottom cut hanging in the air above chips to calluse.
now ready to pot!
this one was about 4" tall in 91-92? (almost 28-29 years) and now it's like that:
this one is the only one with peeling bark and i am worried that i do not have progeny..so last year i popped a big branch and this year 2 more, not rooted yet, callusing.
