I think that people who buy this know nothing about bonsai and are not really interested in the art. Giving them advise seems rather useless.
That seems a it harsh Auk, everyone starts on this adventure on a different path.
I thought I was rather mild. If someone buys this, without thinking, without knowing what they buy, not even know what species they buy, then they are not interested in the art, they've just bought a funny looking little plant.
It has got nothing to do with bonsai, and shows no interest in bonsai at all.
This tree will be dead in 2 months.
I am comfortable in the knowledge that I have a lot of sticks in pots, it's fun and I have no fear of people giving me a bit of a poke when I do post a image of my sticks.
I have my fair share of 'you never know what it may become in the future' sticks.
You are trying to grow your own trees and you are trying to learn the art. I will never ridicule your trees and your attempts to grow and learn.
I will not stop frowning upon people who impulse-buy something, don't know what it is, don't know what to do with it, and have no real interest in bonsai.
