1)By wiring and/or clip & grow
2)Hard to say as many factors affect growth (ferts/sun-levels/soil it is in/etc guesstimates are about as accurate as can be had other than counting growth-rings
3)Gotta check that one - usually deciduous things need dormancy, google it for better answer
4)No such thing as 'bonsai' food. Bonsai simply means "tree-in-a-pot". There are different ratio ferts that are used for each species, but usually 10-10-10 or such is adequate - do NOT fert just yet; we have some ?'s about history of tree, and better to not fert than to over-fert, OK?
5)Depends on what you mean 'grow'...kind of an open question. Growth *should* happen entire time that tree is not dormant, in essence, and 'growth' can occur under-soil with no evidence visually. it would be better to say tree is healthy rather than say its 'growing'. Not trying to split hairs on this, but it does appear that you need to review the 'basics' of trees-in-pots and not worry about 'expectations' for now, OK?
We will be happy to help you, for darn sure, (and welcome to Board!) but the most absolute important aspect at this time is patience, patience, patience. Nothing can be 'sped up' by any means, and genetics rule the species. It will only do so much no matter, and objective is to keep it healthy
- not to get something 'like a picture' that you think looks great
With *time* (and patience, of course, LOL), you *can* get a picture-perfect specimen, but sometimes takes decades to do so. Always begins with good habits and proper healthy methods, blah, blah...
Pics need to be 'hosted' at some place like imageshack or such - nothing uploaded directly to this site, fwiw.
Been there/done that...if you go find a semi-recent thread on 'mimosa' ( I think), there's some other sites mentioned there which I used myself. Possibly if you look at 'details' of other pics losted (link details, per se) you can get a better idea.
For now - read the stickies at top of forum thread-listings, and also www.evergreengardenworks.com/articles.htm ->GREAT info there, and almost considered biblical-style writings
And that is only scratching surface of things-to-know
Forgtall you knew about potted plants as trees are not the same. At all....
(short on time, so my answers are succint - will answer w/ more detail a bit later today, I hope)
