Next steps for the new lawn

So it can't be due to lack of water. Water three times a day. So in summary, I should first apply fertilizer and as soon as the grass (about 10cm) is tall enough, mow regularly. The small weeds will then be displaced by the thickening grass.

Right?

In principle yes, but if you water three times a day, something else is not right

That was sown exactly two weeks ago, freehand and with a bit more seed per sqm than necessary. Two decent heavy rains additionally washed away some seeds. That’s why it’s a bit uneven. However, I have already sown again.

It looks more or less like this with us too, I just posted the worst spots for you. However, I still think I used too little seed. As soon as the lawn is mowable, I will spread more seed after mowing.

OK, that sounds better. But if you have such a bad area, what speaks against raking it up again now and reseeding it?

I've thought about that too, but then I have to wait again to mow because the new spots are still too sensitive, right? And if I wait another 3 weeks now (6 weeks since sowing), I would cut the lawn from about 10 cm to 6-7 cm and overseed the still bare spots by then. Or would you do it differently?
