Why doesn't Mimosa pudica grow?

I've been dreaming about this plant for a long time. I really like that it seems to be really shy when it hides its leaves when touched. I studied a lot of information about growing on the Internet. Everyone says that this is a rather unpretentious flower, which is generally considered almost a weed. But out of 12 seeds, only 2 of my seeds sprouted, and even those were quite weak. In 1.5 months they reached a height of 3 cm and did not grow any further. What could be the reason? Share your experience, please.

Maybe it needs additional fertilization?

In general, mimosa is still not for home growing; they really need light. Try to plant good soil from someone you know, not in bags, but soil from the dacha. And place it on the windowsill with a lamp.

Maybe she doesn't have enough light? Mimosa loves bright light. And I also heard that you can’t smoke in the room where it grows, otherwise the flower will wither away from the smoke. And drafts are very undesirable. This is a rather delicate plant.

If you have a warm balcony, then it’s better to put it there. Mimosa loves light and clean air
