Answer: acorn bonsai
preparing a bonsai starting from the seed is certainly a complex undertaking, which, however, gives great satisfactions; right now, however, you have to be patient and allow your plant to develop at its best, to make many branches, to vegetate until it reaches acceptable dimensions. And it is not simple, because the oaks do not always adapt to live "in captivity", that is in pot.
So, right now, try to keep the plant healthy and in shape by watering it when the soil is dry, fertilizing every 12-15 days, with a bonsai fertilizer, and checking that it does not become ill or is not prey to insects.
The young oaks are very sensitive to powdery mildew, so remember to avoid watering the leaves; and even if it were to be attacked by this fungus (you recognize it from the leaves that seem to be covered with a white patina, like flour), it uses a sulfur-based fungicide to eradicate it.
Keep the plant in partial shade, where it can enjoy a few hours of direct sunlight, but only during the coolest hours of the day.
While the oak develops, it tries to accommodate the characteristics that will make it a bonsai, and to modify those that make it an oak still not bonsai.
So, if you wish, you can think of wrapping the twigs with bonsaistas, so as to allow the branches to develop in the way you want; but remember that, being the plant still young, it develops quite rapidly, and therefore the wire will be kept very loose, and removed as soon as the branch tends to grow too much, or else the wire itself will cause the presence of showy signs on future branches.
If the plant produces long twigs, shorten them periodically, when they are still green, leaving only 2-3 leaves for each branch; also in this case your password is caution: the plant is young, has few branches and few leaves, it avoids leaving it almost bare; in fact, your plant grows thanks to the nourishment obtained from chlorophyll photosynthesis, which occurs in the green areas of the plant, or in the leaves.
Avoid excesses in every sense: avoid excessive heat, excessive shade or insolation, excessive watering or drought.
Since it is a very young plant, you will also need to allow it to develop a good root system, so avoid placing your plant too early in bonsai pots; right now it is very well in a common vase, even in plastic if you want, where it can enjoy a good amount of land.
