Hi nizmo
I had to repot 3 flowering plants one time and all I did was get a larger pot and filled it till the plant Iam repotting is level with the top of the pot.Set the plant that you are repotting in the pot and fill in with good soil around it.Remove the potted plant from the bigger pot and remove the plant from its pot.I gently losen the soil alittle and place it in the hole I made in the larger pot.I sprikle some root tone in the hole and on the root ball and place in the hole.Water litely and watch it start to growing again.It slows the grow down alittle but starts back better than ever.It worked for me ,hope this helps,but thats all I know about it.
