I have several bald cypress tree seedlings planted in by back yard. They are approximately three years old. I would like to place them in containers and train them as bonsai. I have some questions and hope I can receive information before taking any action.
1. When is a good time to pot them? (North Texas)
2. Should I trim the roots before potting or leave the root ball alone after I dig them up?
3. What size container should I use?
4. Should I use "Bonsai soil" or just garden soil?
Thanking you in advance for your advice.
