After planting some seeds from storecitrus I got my first result about 2 days ago!

Congrats!

Some updates...it seems that I've got 3 'siamese twins' growing

When and how can I cut the seedlings to form branches? I know I red it somewere but I seem to have lost that part of information.

It's certainly too early at this point. I would say after 2 years, and even then I would probably not do it, unless they really grow too high (> 25cm or so) without branching out by themselves

You cut the top off the main branch & it will force branching below.

nice seedlings !

better never cut, it could make the plant never bloom and fruit or as late as after 20 years ...

Where do you get your information? I have put up with a lot of nonsense, but if you don't know what you are talking about then stay silent.

You remember the node counts ?

If you cut them, then you never let it get the amount of nodes it needs to mature.

That is the reason many pot growers have citrus trees, that never bloom or just after 20 years or even later.
Just by cutting them regulary and form a neat small bush ...

Well, it's not quite like that. Just by cutting/pinching off the tip of the seedling you decrease its node count by the number of nodes removed. If you pinch only the apical bud the seedling will regrow it in as little as one month, or even less in growing season. It definitely doesn't mean that its growth will be stunt or its maturing delayed. Constantly pruning an immature seedling is something else, and will eventually result in its delayed maturing.

Yes ...

In many forums user ask, why my citrus tree never blooms though it is 20 years old ...

They just prune it all the time ...

If I understand correctly, neither Mark nor Laaz suggested heavy pruning. The advise was (again, if I understood correctly) to cut the top sacrificing just a few nodes to force branching and, therefore, to establish a stronger tree structure.
Greatly simplifying things, say, you cut above the node #15, so the branches will start from node #16, not the first one. Am I right, Laaz?

Nobody said it should be pruned all the time.

I just know my fellow europeans who always overdo it and then result in trees that never reach the nodes to be mature and bloom ...

Therefore I said, it is better not to prune at all ...

GT you are correct. On large seedlings I top @ 18-24"

Laaz, thank you very much!

I am quite convinced that it is a good idea to cut the top even on seedlings.. I did not do it (out of curiosity) on one Valencia seedling and it grew taller than me without a single branch!
