Jades, I love them (Portulacarias and Crassulas

)
--> The first one is a monster... the left "trunk" is 5 inches, perhaps this one takes the "natural" look of a jade better?
Its gonna flower soon, I might post a pic when it does
--> 2nd one is a little Shohin, found it as a neglected cutting last year, hah hah
--> 3rd one is a cutting taken 4 years ago in my first year of Bonsai, one of two trees that has survived its first year with me >xP
How does one reduce the leaf size of a Crassula Jade?
