    Hi

    we moved into our new home in november, we have this bush in the front garden (i'm not sure what species it is)

    [​IMG]


    working in the garden over the weekend i noticed that the leaves towards the bottom look in pretty bad shape

    Any ideas what could be causing this and how to cure it, its a lovely bush and we'd hate to loose it

    Hi Pete, Not sure, but it looks like it could be one of the Viburnums to me.. :scratch:

    :thumbsup: I would just remove all the lower discoloured leaves & dispose of them & give it a feed when it has finished flowering..

    Hi Pete .
    Looks like Viburnum tinus to me .a good winter flowering shrub ..
    Damage may be due to Viburnum Bettle, Most of the damage is done by the larvae, which can reduce the foliage to lacework during May-June.

    I agree with Marley and Dave it looks more like insect damage from beetles, weevils etc rather than disease. I think Marley advice to remove the dead leaves, and the damaged leaves from the bottom, is spot on, as well as giving the shrub a sustained program of feeding just to get it back into robust health. I don't know if Dave or Marley would agree with but I think a gentle pruning of the tips, after flowering, will encourage it to sprout from the bottom because, if you'll pardon me for saying so, it looks a bit top heavy.

    It certainly looks top heavy .Some light pruning would do no harm ,but not sure if that would be enough to encourage new growth lower down .
    Feeding would also help.

    I was thinking of a light pruning because of the poor state of the shrub and not wanting to give it too much of a shock until "it's got it's feet again". But then again maybe a medium cut might not do any harm, Dave!!

    I'm not sure as to what it actually is, but one thing that strikes me is that its insect damage from last year, rather than disease.
    So actually removing leaves now will achieve nothing other than weakening the plant.

    I'd leave well alone and make sure I spray next summer at the first sign, should the same problem appear.

    Any really damaged leaves, the plant will shed of its own accord.

    Pete, Marley wan't recommending the taking off of leaves that were of some use, he was recommending
    just the removal of the dead and damaged leaves. If you look at the photo's the damaged leaves are so
    bad that they doing nothing for the plant regarding photosynthesis or the production of sugars, but the decay
    in them could encourage disease. I agree spraying the plant would be beneficial once the insects are on the move again.

    Watchit Mate, he is a she.:D

    I just thought it would be a tedious time consuming job that the plant would probably do on its own accord in a month or two.

    thanks for all the advice :) I've never owned a garden before so i'm learning as i go along

    couple of questions,

    what sort of fertiliser should i be using?

    the spray thats mentioned, is this an insecticide?

    An insecticide, in summer when you see signs of the insect attack on the new leaves would be my advice Pete.

    Thanks Pete, and my apologies to Marley. I should have checked your profile Marley. To err is human but I will get to know people better as we go along. Again, Marley, my sincere apologies!

    :WINK1: Yep I am a she.... Armandii :heehee: Makes no difference I still stand by what I said about removing any old & damaged leaves..... Plus I am a great believer in tip pruning Armandii as well.... I do it to my Euonymus & Hebe shrubs too & they stay small & tight... :WINK1: :thumbsup:

    Problem is when you got lots of bare stem, then heavy top growth ,its not so easy to stimulate new growth from below.

    If it was mine I would wait till after any late frosts, cut hard back,Topdress around the base adding some general fertiliser. This would force out new growth which would then harden up before next winter .
    Drastic but I could not live with the bare stems .

    Marley, be careful with the secateurs around Armandii!! I still agree with your recommendations and
    think that a drastic cut would be risky as the plant has been neglected and it under par at the moment.
