My little persimmon stopped stretching upwards and is now for a few days staying at more or less the same height. It has sprouted four leaves and stayed there. And it will probably stay there for a while now, nothing much outwardly visible will happen, while the seedling will be concentrating on building a hard wooden stem and nice strong roots instead of the mushy soft ones that consist of 90% of water. That is what allows for the quick growth at the beginning, by bloating cells with water – and it is visible now that the stem got actually a lot thinner than it was a week ago, as it lost its water content.
Since I want the tree to grow nice and straight upwards for a while, I turn it about 10-30° counterclockwise every evening. Also I am taking care to not over water it – it is colder on the windowsill than it is in the rest of the room, and I do not want the roots to rot. I will have to try to find information in my library about how much water persimmon actually wants to have – there are plants that need a lot and plants that need very little, and I have lost bonsai trees (sometimes quite valuable) to both under- and over-watering. So far it seems to prosper.
