Why do I need to plant seedlings to sequentially bigger pots? Why isn't
possible to plant a seedling to just 1 pot - the final size required by the
adult plant?

I've wondered this myself Gareth. In the wild seeds just drop to the ground and
grow OK without being in pots at all!

In the wild, there tends to be other plants around taking up water. In a
pot, the soil seems to go a bit stale if you've got just one tiny
seedling sitting in the middle taking up water very slowly. Totally
non-scientific! Possibly utter rubbish. But it's how it feels.

It's a matter of degree. If it's fast-growing, you can put into a lot
larger pot than you would, say. a cactus, which may require a whole year
to go up half a pot size.
