Fast Growth In Pots
Michael Hagedorn noted that the myth of no plants thicken trucks once in a bonsai pot is not true for all species. Here are a few notable pot-happy trees.
Larch
Wisteria
Trident
Styrax
Contrary to those fast growing species, the following are the opposite and growth should be invested in the ground:
Spruce, especially Ezo Spruce
Juniper
Hornbeam
Beech
Stewart’s
Atlas Cedar
