Hello there ;-)

About 1.5 years ago, I installed a roll-out lawn that has established well.
At the beginning of July, I decided to aerate, overseed, and fertilize it a bit (I fertilize regularly).

I have always used a natural fertilizer from the company Schwab. However, for the last fertilizing, I used an NPK fertilizer from Eurogreen.
I aerated using the Einhell electric aerator.

Now, I have severe patchiness, partly white in color. I can't see any fungal growth.
In these areas, the grass leaves are also thinner than in the still (lush) green parts.

Here are some photos:

Garden with irregular green lawn, brown dry spots, border hedge, and paving path on the left.

What happened here?
Overfertilized?
Incorrect overseeding with a less durable seed mix?
I would appreciate your assessment.

It’s not quite a dust bowl yet; depending on your standards, you can just leave it as it is. That’s what I always do—during wetter periods, it turns green again. And I even park my G-Class on it 😉.

Instead of the G-Class, I prefer to ‘park’ my grandchildren on the two-week-old roll-out turf 😉
Watered twice daily, well rooted and established, though slightly uneven in height, but a deep green. Probably mowing for the first time tomorrow...

There is no need to reseed a roll-out lawn.

Yes, actually. I removed annual bluegrass (Poa annua), and that naturally leaves bare spots.

If the lawn is cut too short and too often, it will burn. This applies to any type of grass. So, less is more.

In addition, the lawn needs to be watered more frequently on hot days. The turf shown here has a water issue, not a fertilizer problem.

It also depends somewhat on the soil underneath. If it is heavily compacted, it won’t retain moisture, and the lawn will burn as well.

So, water properly and it will look nicely green again in 3 to 4 days.
