When growing out trees in large pots for thickness... what about using root
mulch as the soil medium??

some of the problems with mulch depending upon the origin of the
material used a
1. if it is not broken down it can rob nitrogen and other nutrients
from the plants growing in it, requiring more fertilizer to get the same rate
of growth.
2. if the mulch has not been heated to a high enough temperature it
can contain pathogens that will attack your plants.
3. depending upon the source the mulch can contain toxic chemicals
including weed killers.
A sort a related story - fellow in my Florida neighborhood dug black
muck out of the ditch behind his house and put it on his vegetable garden,
all his plants died, the ditch had been sprayed with weed killer by the
mosquito control district.
Know where you soil, mulch, etc., comes from before you put it on your
plants.
