Ok thank you all. Videos I've watched so far are showing a bonsai re-poring a grown bonsai. I'm still unable to find out how a grown seed got that shap. I had one in my garden five years old but still a fresh grown plant a thik one, even once it brought fruit too. Do I have to cut some special roots ? But when? Or branches? Or just the seed let grow? I've seen many videos wiring, cutting etc but all were grown bonsais. Wanted to know what to do and when to do after the seed grown. The very first steps.

Sorry, the thin one I mean, it gained a hight of about 2.5 feet .Berries.

Re-poting
Sorry gentlemen writing without glasses wasn't a good idea.

Bonsai trees are just ordinary tree styled artistically and traditionally. repotting is just to refine the root system and to improve it for nutrient and water uptake. Th siring techniques are the same a the videos you watched. Maybe someone else can explain it better than me.

Basic guidelines in the topics you are suggesting. You can find them here:

www.bonsai4me.com/Basics/Basics_StartingOut.html (Few basic advises to read from the very beginning)
www.bonsai4me.com/Basics/Basics_Propogation.html (Here you can find the three fundamental ways of propagating a tree)
www.bonsai4me.com/Basics/Basics_Repotting1.html (This is the Part I of repotting, at the end you´ll see Parts II and III)
www.bonsai4me.com/Basics/Basics_Pruning1.html (Pruning Part I, there are two more Parts)
www.bonsai4me.com/Basics/Basics_Wiring.htm (How to wire a tree and its branches)

Read them carefully, you´ll learn a lot of things. Also, surf the site thoroughly, you´ll see there is much more in Bonsai than just dwarf or small trees placed in small pots. Also, it would be of incredible help if you could join a club. People would directly explain things based on their hands on experience.

I also believe that the general requirements of bonsai pots is good quality info and, in a future, it might help a lot those of us who are still in the beginnings

Absolutely, and though I do know the guidelines, more or less, this is quite specific so I'll keep it for later reference.
However, this concerns someone who wants to start growing bonsai from scratch - your reply is not relevant for him.

For growing trees, I would simply use large pots, giving them enough room to grow.

This is one year old 37 inches long . Now what to do with it so it stop gaining hight and start shaping a trre?

What species is this? It doesn't seem like something that's suitable for bonsai.
First, get it out of that can, in large pot and plant it in decent soil.

Next, let it grow. Bonsai do need to grow. You do not want it to 'stop gaining height'.
To reduce the height, you cut off the top. Don't do that yet, first repot it and after a few months, when it's doing well, come back with new pictures.

Could it be it's a Ribes? Probably not the best choice for bonsai, especially for a beginner.

This is it. This tree sorry I don't know the name
