Rolled turf - Various problems from the beginning

Hello everyone,

after our new building was finally completed in December, we had our garden laid out at the end of May. Unfortunately, we had a bit of a falling out with the company that laid out our garden. That is why this company is not our first choice for obtaining information.

We have a total of about 80 sqm of lawn area on which Sport&Play turf was laid.

According to the gardener, some fertilizer was applied directly under the turf. About 60 cm of nutrient-enriched soil was spread and compacted under the turf.

Unfortunately, we had the problem that our turf was laid at a time when the midday sun was already around 25-30°C.

Now our Sport&Play turf has been laid for about 8 weeks.

Unfortunately, we have had problems from the very first minute.

1-4 weeks = Watered daily with about 15L/m², nevertheless the individual turf strips were visible and there were gaps between the individual strips.

When walking on the lawn, you felt a strong sinking sensation. As soon as you mowed over it, you could also notice how uneven the turf surface was.

4-7 weeks = Watered daily with about 10L/m², the individual turf strips were no longer visible, but the lawn still appeared uneven and you had the feeling of sinking when walking on it.

7-8 weeks = The summer temperatures are currently exploding, so now I water on day 1 with 20L/m² and on day 2 with 15L/m², and yet the entire lawn area appears green/brown in many places, the lawn looks dried out! When walking on the lawn, you no longer sink in.

The irrigation always runs depending on intensity between 11 PM and 3 AM.

Irrigation is done with household water and a Gardena irrigation system.

Now our question would be:

- Why do we have so many brownish spots despite this amount of water?

- Is there a way to make the lawn a bit more even (currently it looks rather uneven like cobblestone)?

- Should we perhaps fertilize? If so, is that even possible at the current temperatures?

- How should I adjust the irrigation amount or the irrigation period?

Thank you very much

Tanning is like this. Fertilize in the heat! Otherwise, you’ll burn faster

Just did it? Not anymore now

One can hardly understand that. Please "speak" in full sentences.

I think with the current temperatures it is simply hard to keep everything 100% green. I would continue to water and observe. Right now it is very hard to say anything about the condition because unfortunately it is too hot. You have to be careful with the fertilizer in the heat, that is probably what HilfeHilfe tried to say, I have heard of that as well.

For me, the lawn looks great given the circumstances. It cannot have developed deep roots in such a short time. You are watering exactly right (only once a day with a larger amount), which promotes deep root growth. That it is uneven can really no longer be changed. That was messed up a few weeks ago. You would now have to remove the turf, smooth everything out, and lay it again evenly. You can still protect the lawn by mowing very often and thus only cutting 1-2 cm each time. The mower blades should also be very sharp. Furthermore, with the hot weather, it should not be mowed too short so that the lawn can provide shade for itself.

Isn't it the case that the lawn becomes firmer after rooting with the substrate?

The entire subsoil becomes firmer, as it also has to settle first. The topsoil cannot and must not be compacted too much.

The OP wrote that you no longer sink into the lawn.
But the unevenness will probably not go away any further. Apart from that, no unevenness can be seen in the pictures.
