I have 2 Jolly Tigers that are trying to revert back to all green

#1 tree has no variegated leaves at all so I dug down around the trunk and saw some nice striping on the trunk below the soil level so I cut the top of the tree off hoping that the bud on the stripe part of the wood part will be variegated when it pops 

       

Tree 2 has a variegated leave at the bottom but the top is trying to revert back so I knocked the top off just above the variegated leave hoping the lower bud will b variegated when it pops 

I'll post some pictures when the new buds pop and see what happens 

     

Hey Dave. Be sure to keep us posted, very interesting.

Hi Dave,
Those trees are trying to survive . Aren't you afraid to kock them totally ?
If those were mine I would let them grow as is.
For me once the trees have more energy and more sun hits them - variegation on variegated plants shows up more when sun hits them directly-, new leaves will be variegated.
Of course, the trees are yours and so is their destiny :)
