three years ago, we had a hedge planted along a total length of about 40 meters (130 feet) using Caucasian laurel (Prunus laurocerasus 'Caucasica') from a nursery. The plants were about 150-160 cm (59-63 inches) tall at that time.
We water the hedge during extended heatwaves and also regularly fertilize, prune, and care for the plants.
Still, the hedge loses almost all its leaves every year around April/May. Even many new small leaves turn yellow and fall off within a few days. This is quite frustrating because after three years, the hedge is still not dense due to the repeated leaf loss, which almost always happens between April and May.
I have read about possible causes online, but there are many different explanations listed—from underwatering to frost damage, or too little/too much fertilizer, and so on.
Our soil is relatively loose, meaning it’s more of a gravelly base. We have about 15 cm (6 inches) of humus, and underneath it is very rocky, with gravel and sand.
So, waterlogging is certainly not an issue (which the plants dislike). I make sure to water the hedge properly at least once a week and fertilize it twice a year. I’m honestly quite puzzled about what the cause could be. I know it’s difficult to diagnose from a distance, but maybe someone has had a similar problem and can offer advice or tips.
Thank you for any possible help.

webdesigne10 May 2018 19:23According to a gardener here, the issue is likely due to a lack of moisture because we have a gravelly soil, which means we would need to use the drip irrigation hose almost 2-3 times a week since the water soaks into the ground very quickly...
And why does the gardener plant something for you that is not suitable for the soil? I go to the gardener to get advice on what grows well there... After 3 years, you will probably have little chance of insisting on a replacement. I don't have any affordable tips. I would look for another gardener and ask what would grow better in the given soil.
