Lawn care after winter - How do I proceed?

Exactly, and if you are going to scarify, then fertilize at least 2 weeks beforehand. Scarifying is not necessary for you, as the lawn was only freshly laid.

I have to admit, I always fertilize and sow after scarifying. The soil is loosened then, and in my opinion, fertilizer and seeds can penetrate best.
Whether that's correct, no idea.
Yesterday the last bit of snow melted here, so I am still waiting until it is a bit warmer at night.

It looks exactly the same for me.

Since I was also concerned about the question of the right time to fertilize, I came across the following aspect in another forum.

The main consensus is that fertilizing should start once the cumulative daily mean temperature reaches 150 degrees Celsius. Because the plant does not know our calendar. From this temperature on, the lawn apparently needs the most nutrients to compensate for the strains of winter. If the timing is missed, you probably spend the whole year playing catch-up.

The big problem here is that this temperature for weeds is already at 120 degrees. So if you wait too long, the weeds may gain the upper hand.

If you fertilize beforehand, you already have the energy in the soil or in the lawn. The fertilizer also needs a certain amount of time to reach the plant.

I'm not a gardener, but in the groups where the topic is discussed, it is always recommended like that.

Fertilizer: Only makes sense once it grows. It grows mainly at more than 10 degrees during the day. So it's still a bit early to fertilize. I advocate patience. Our lawn also looked bad after the snow melted, but it is gradually recovering. Only growth is not yet visible. Only that it is turning green.

You can see more sunlight every hour at the moment.

In front of the house [Frühling], everything is growing
Behind the house, the last ice remnants are bravely fighting to survive. It is supposed to get colder again now.
Dandelions and co are already growing well again
