Cherry laurel Caucasica - yellow leaves every year??

Sorry but 2-3 times a week drip irrigation. You'll go broke doing that. After 3 years they have to grow on their own.

Yes, I know all that myself as well. I just thought that maybe someone might have an idea or had a similar problem.

Only the cherry laurel can grow in our soil. It is otherwise quite undemanding, but since it loses leaves every year, it will hardly become dense.

It was a nursery from Hungary. Actually, they have a great rating and I was very satisfied with the service overall (they had exchanged some without problems at the beginning). Unfortunately, they did not take a soil sample and just delivered, planted, fertilized the hedges and that was it. I was supposed to wait for the rest, but after 3 years they should have settled in somewhat....

Maybe they are too close to the wall?

I am not a plant expert, but I consider that quite likely. If there is possibly a concrete foundation under the soil, which also absorbs water nicely, and then the wall heats up nicely on the first sunny days, the plants might initially be overwhelmed by heat, UV radiation, and dryness after the long winter. In which direction do the wall and hedge face?

I don’t know how others see it or if it depends on the variety, but for me, they are too bare and not branched enough at the bottom. I would cut them back further in spring so that they become denser at the bottom.

According to the nursery, the wall does not matter. On the contrary, it protects from the wind. One part gets sun all day, and on the other side only in the afternoon. It doesn't look necessarily much better there now.

The roots have about 50cm of space to the wall, as the nursery also planted it, which should be normal. No one plants their hedge 2m away from the property boundary.

Thanks anyway for the tips.

In our area, you can clearly see in winter which plants are protected. They look significantly better in spring than the free-standing ones, which have frost damage on branches here and there. That shouldn't be a problem for you at all.

The roots have about 50cm of space to the wall, as the nursery also planted it that way and it should be normal. No one places their hedge 2m away from the property boundary.

So either the picture is distorted or the 50cm are not correct. To me, the distance in the picture looks like about one row of stones. Since you have 10 rows of stones and the wall is certainly not much higher than 2.50m, I assume that one stone has a height of about 25 cm. If the concrete foundation in the ground is even a bit wider than the wall thickness, then there is even less space underground to the roots. In our case, the lawn always turns yellow or brown at a distance of 50cm from concrete foundations. You can water as much as you want.

I don’t know how others see it or if it depends on the variety, but for me, the ones below are too bare and not branched enough. I would cut them back further in spring so that they become denser at the bottom.

Just read up on it again. It could definitely be due to the variety Caucasica, which is very narrow and grows tall.
