I never understood what the big trouble with transplanting is.
This is a tough plant guys. It can handle it.
Water it turn it upside down into your hand and plant it in a new pot with more soil.
Simple.

I understand wanting to be gentle and not wanting to stunt the plant. But I would have to rip it out of the ground to stunt it.
And it would probably still be fine.
Remember to plant it a little deeper then were it was. That way the new roots will grow off the new stem under ground.
Plant it right about where the Embriotic(round,first)leaves were.

If the roots are growing together ,just cut off the part that won't let go.
If they are growing together big time,then cut around each one with a butter knife.
