I was wondering about what to do when repotting with a sheen that is so dense water doesn’t penetrate it, should you go in there and replace the soil while leaving the outside of the root ball intact. I was thinking about this when watching the Azalea repotting archive video. They kind of mentioned this in the video but didn’t really provide an answer to what to do in this situation. Their “quick fix” was to either dig a hole so the water would kind of pool up and then soak into the sheen or to insert a tube that goes directly below into the sheen. This question is not pointed specifically at azaleas but more in general I guess. I kind of wanted to know for trees in which we don’t fully bare root i.e. pines and most evergreen trees.
So I guess my main question is should you ever go into the sheen and remove the soil completely, as Akadama and/or Kanuma will eventually break down, to replace it on Azalea, Pines, Junipers and other evergreens species?
