Repotting and the 5:1:1 mix
Im curious about about repotting nursery plants into the 5:1:1 mix. Does one just throw them in the standard way and eventually the soil and soilless mix together as the roots start to venture into the surrounding 5:1:1 mix? Or does one try to reduce the amount of original soil by as much as possible to ensure the benefits of the new medium?
My main plants are: camellias, azaleas, gardenias, rhodos, loropetalums and a couple of maples. I can understand removing soil from maples during dormancy is ok, but what about the rest? Can they be thoroughly bared and replanted or will this kill the plant? I want the plants to get the most out of the medium, otherwise, I might as well just pot up in the standard way? Also, do I have to wait until the plants are root-bound to repot? Say, if I buy a fresh plant from the nursery and in it's standard soil and not roo-tbound, is it worth it, or possible to refresh the soil straight away and any time?
Hope this makes sense.
