My Laurels leaves are black

Hi 

Hope you all can advise me on a problem I'm having with Laurel hedging at the front. The leaves on the top of the hedges have turned black very quick. I have attached photos. It is an infection? Hope you can tell me what it is. 

Thank you.

    I think that’s frost damage on new young growth that was triggered by the warm spell in early March. 

    As soon as we stop getting these night time frosts you can give your hedge a hard trim to thicken it up and it’ll be fine. 

    Lots of info here on how to grow a thick  and healthy laurel hedge

    Actually may I disagree? This is not a Laurel, it is Griselinia. Can be a bit frost sensitive.

    Having opened my eyes put on my specs and drunk a bit more coffee I have to agree with you @Pianoplayer 👍

    ... but I think you’ll agree that the trimming advice will still apply?

    @Dovefromabove absolutely! Mine has this every winter, and gets hacked back ruthlessly - has survived nonetheless!

    I don’t think they do too well in colder windy areas do they.
    They grow a lot of hedges from it in Cornwall where it’s much warmer. 
    Ive always been reluctant to buy them for that reason.

    Thank you for your advice. I know now for the future. Wasn't aware frost would have that impact.
