Wiegela diseased?

GrumpymumGrumpymum Oxfordshire Posts: 76
My variegated wiegela did not flower very well this year, and when pruning back some of the old and dead wood today, I  found this branch which is rotten in the middle. What is this, and can it just be pruned out, or does the whole shrub need to be removed?

    Certainly remove that branch. You can take cuttings at this time.  If they take, you can replace your Weigela with a new one.
    You don't stop doing new things because you get old, you get old because you stop doing new things. <3

    It looks like it might be damage from a moth caterpillar.Was/is there a hollow chamber in the dark section?
    Some species burrow and pupate,  little areas like branching joins and old wood like your photo are ideal.
    Nothing to worry about there although it could rot further and get diseased you will be cutting it anyway.
     
    Some parts of our very old Weigela are rotten it has a large old base. But cutting back as already mentioned they will sprout away.

    Thanks, yes it was sort of empty near the top. Have pruned it right out, will take some cuttings just in case.

    Thanks all for your advice.
