Hey Evie,
Jiffy's right on the money with that info!!!!!
The only other tid bit of info I'd offer
is the individual leaflets also do the
same thing, if one falls off,
or you gentley pull it off it will also
grow from the base of bottom of the jade's leaf..
A very easy
plant to grow...
Also, to my understanding, Jade's really like to be root bound so leave the momma there like Jiffy said....
Will Creed comes through from time to time and he may be able to offer additional information about them to help your further...???
Weezie
