I keep and create my own bonsai.Feel free to ask any questions!
For basic info, in case it's not known... Bonsai are simply certain species of shrubbery/junipers/trees that are continuously trimmed (in specific ways, depending on the design) annually to keep them small. Most are planted in the ground to grow for years first for the trunk to thicken, amplifying the "miniature tree" look instead of just a small plant, before being potted into a small bonsai pot.
The easiest bonsai to start with is a juniper. I personally find it much more fulfilling to buy a small-medium sized juniper from a nursery and trim and train them into bonsai myself.It's not difficult after research. The typical bonsai selling to the public are just overpriced for the name and not well-trimmed... most are even just cuttings (small branches) from a larger tree and stuck into a small pot.
