Sorry, last thing I'll add.
Just remember, this is a very early work in progress. Get more trees. You are going to be touching this tree maybe twice a year for the next 3 years at least, before it starts getting the trunk you want, another year perhaps then you can start working on branches.. primary branches might be a year of no touching for thickness... etc etc.. Years add up. Dont wait for it. Buy more.
Its what everyone on here screamed at me and STILL DO. Its a long game this Bonsai malarkey, the more trees, the better.
