Prunus laurocerasus turning brown

andrewgough

Hi Guys, 

First time posting so appreciate anybody who feels they can help.

I have these Prunus Laurocerasus planted in October, there was a total of 60 planted and a small section close to the road have turned a brownish colour as the picture attached. I was wondering if anybody had any advice on the best solution to combat this, from what I have read online it could be a Fungus but I'm unsure so I thought I would post to some experts

Does anybody have any suggestions on what I can do combat this?

Thanks in advance

How tall are these shrubs? They look quite mature to me. At this stage, not totally convinced it's anything fungal, could be some type of chemical burn or a liquid has dried and the leaves have been scorched by the sun and light. Whether it is fungal or some type of burn, they will need to be pruned off soon. But check the base of plants are firmly planted in. Larger sized shrubs are harder to 'take' to their surroundings. Mulching and watering are also key tasks for any new shrub for the first 2 years.

Thank you very much for the reply, thats very interesting, maybe something could have sprayed from the road side, it seemed to happen after snowfall we had so maybe something to do with this, 
the shrubs are in the region of 2 - 2.5 meters, I was watering them often in the first few months but I actually though they had established, so do you think I should just water then often at first and see if thats loves the issue? also do you think a specific kind of feed would help?

Thanks again

There's probably no need to water now, but as soon as they weather warms up again in mid spring, water it when there has been no rain for over two weeks. The key is to water properly directly into the roots to allow the water to soak right into the base areas. Best times are late evenings or early mornings to avoid losing any water due to heat. With shrubs, a good thick layer of either compost or rotted manure on top of the current layer once a year especially newly planted shrubs should be sufficient feeding.

Prune out the affected areas when you have the time and hopefully, there will be new growth in later spring/summer.
