Viburnum Tinnus Prunus looking poorly

Hi all, hoping someone might advise on what could be causing our viburnum's  leaves to go yellow and fall off?

I'm thinking it might be a leaf fungus problem. We planted it (as a mature shrub) on the site of an old leylandii, 6 months ago. I'm not sure whether it needs feeding, or if the answer is to spray it with something?

Any advice would be very much appreciated.

Regards

Paul

    Check for red spider mite, because if previous  leylandii, if you find any you could overhead water when plant is in shade as they don't like damp, there is probably a spray but I don't use them so can't help. 

    I am sure someone will no what it is image

    Thank you Cathy - I removed a load of bad leaves last week but didn't notice any little beasties on them.

    Hi Paul - the only pest that Viburnum  really suffers from is the viburnum beetle. Check to see if that looks like the damage your shrub has. They're tough shrubs so if it's established well enough that might be the problem.

    Did you manure the soil before planting? Only Conifers are notorious for depleting the soil of nutrients. Also the conifer would acidify the soil. t Viburnums are not that fussy about pH, but if the soil was very acid it would not be happy and you would get some chlorosis, as your picture shows.

    I would give the shrub a real good feed with Miracle Grow and see what happens.

    Thanks all - I haven't seen any beetle trace Fairygirl, so I will have a go at feeding as you say Berghill. We did put plenty of compost in when we planted it. We planted a Red Robin at the same time close by and it looks in really good shape although it is a couple of metres further away from the old Leylandii site.

    Good there's no bugs. image

    Berghill's advice is spot on re adding lots of nutrition to the site. Lleyandii's a nightmare if it's been in there a while - nothing else survives round about it. Make sure the Viburnum's well watered during long dry spells till it's looking happier and putting on plenty of new growth. I'm sure it'll be fine. image

    Many thanks all, much appreciated! I will give it a good feed and water and hopefully all will be well.

    Cheers
