Current lawn condition - Next steps?

I mow 1-2 times a week, with a mulching blade. Do I still need to fertilize?

I mow 1-2 times a week, with a mulching blade. Do I then still have to fertilize?

and sharpen the blade sometimes

If yes, what is the best way to proceed here? Or does the problem resolve itself?

Well, mine looked like that two months ago too! I couldn’t get it under control by digging it out. We don’t have a robotic lawn mower yet.
I bought the Compo Weed Killer on Amazon, it does not harm the lawn but helped.
I also bought a pressure sprayer.


After the vacation, I will fertilize the grass again and then it will be perfect.

And yes, there will be complaints again that a wild meadow is more beautiful, etc...

A wild meadow IS not more beautiful, some FIND it more beautiful.

Above all bees

Unremoved thistles, dandelions, etc. have nothing to do with wild meadows either. That is poor maintenance and nothing else. Weeds.
