The topic title explains my predicament quite well. Three days ago I requested a Bonsai Tree on my Christmas wish-list after seeing one of those nice stands in a lovely, airconditioned shopping center and well, my young, eleven-year-old sister decided it would be a sweet gesture to buy one for me.
Two days ago she told me, I started doing my research and discovered the absolute world-wide ... cult (for lack of a better word) that is the decade long art of bonsai growing, wiring and creating. During this time I learned that my sister had made a grave mistake, with lots of information from many different sources indicating that shopping center bonsais are not made for this world.
But I love it. I love my little Dwarf Hinoki Cypress and I want to save it. I'll give you the run-down and then launch some questions and if you can help with any or all of my problems I would greatly appreciate it.
From what I can tell the 'potting mix' is actually pretty good. I was granted exactly 5 minutes yesterday to see this plant and care for it however I could (younger sister attempting to preserve the christmas feel of the present) and stuck my fingers in knuckle deep, as advised, to find the primary roots. I was really nervous about damaging the plant, so it was a fairly weak effort (I fingered through a lot of fragile surface roots... It's a small plant so it would be worse than another plant.) There is a thin layer of what I think are just ornamental rock pieces, not glued down or retaining water - so I've left them there for now. Underneath that there is mostly tambark with some soil mixed in.
In terms of watering I have only been misting the surface of the soil and plant occasionally, scared to death about root-rot. The plant has been getting plenty of direct sun between the hours of 8-12 and 4-9. Apparently the Hinoki is prone to going brown in the inner-leaves because of not receiving enough sun. In Melbourne the last few days have been very warm so I'm not too worried.
But here is what I am worried about.
1) I want this plant to become a true bonsai. If it isn't against the rules, I'll link you a photo on my blog of the plant (if it is, moderator feel free to delete this, many forums of all kinds are so touchy about "advertising") http://parchmentgarden.blogspot.com.au/ ... onsai.html. And by 'true' I mean a few things. I want it to have a bigger trunk, so that it can taper. At it's current small size, I'm reluctant to cut any branches or even trim leaves because I read the cypress is adamant about not growing back from old wood. If I remove some surface roots to elongate the trunk, will I be harming the plant? Also I recognise that at the moment it looks more like a barely manicured shrub than a bonsai, but I don't want to butcher the poor thing... at least not until after Christmas.
2) IT'S GOING BROWN. The tips of the uppermost 'leaves' (they're more like buds) are going brown and it's spreading.I think this is a result of too much sun and or a jumpy transition. This shouldn't be permanent/widespread damage, it's very few buds but I'm afraid it might get worse.
3) Should I repot it to grow the trunk bigger or plant it in the ground (I have space), I'm just worried about the roots growing TOO much and then not being able to pot it again (I may have also read bonsai roots in general are sensitive).
At the moment I might just be killing my bonsai with too much love, but I'm worried. Please help?
I love bonsai, they are so beautiful and I look forward to getting to know many of you, if you'll have me

Thank you, Chris.
