Laurocerasus

Hello. My name is Katerina and I am living in the Czech Republic. On our terrace i am having 16 


Laurocerasus. I have lost 2 already and another 2 don't look well. It always start the same. Leaves are getting stress (like luck of water) but i am having irrigation system, after that the leaves are getting brown and at the end the bush dies. Any idea what could it be? I am feeding it, the soil is wet enough. Plenty of sun. Could it be that the roots could be overheated? I would hugely appreciate any help, views, idea. Many thanks !

It looks like you have more than one in each container too, which isn't enough room for these big shrubs, and coupled with only a small supply of soil, they were never going to be sustained.
Not to worry. I think it'll be difficult to get anything other than ivy to thrive, but you can get some nice variegated ones, which would be a bit brighter, and once established, they cope with virtually anything. You would need a support in the planters first, for them to grow on. I don't know if trellis would make the whole thing too heavy, but it would be the best support. You can clip it into the size and shape you want.
Others may suggest some different shrubs to try, but I'm not convinced many would do well in the situation you have.
You may have to accept that they won't always look perfect either. As I said, I don't think they've done too badly so far, despite some difficult conditions. The ones you've lost may have been a bit more exposed to those conditions too.
Is there any way you can have more soil in the containers, or do they have a false bottom [ or something similar] to prevent that? The weight could be an issue too I expect.
Any potted plant needs some of the soil replaced every year too, if they're staying in the container long term.
You could try replacing your dead ones with just one in the container, and see if that works better.
