Hi Armando,
Nice start .
Keep them together and later -should/can be following year - airlayer the ones you want to pot separately . Later, you can pot them up, all together.
If you try to separate them now or too soon, you might kill them all .
Just my opinion, they are yours, the decision is yours :) .
For the question, for me, my perfect answer is: Rather stick them in the ground !
