Tiny white flies on viburnum

Seems to be tiny which flies at the tip of the the branches on my Viburnum bodnantense DAWN which is killing off the leaves. What can I do to put this right please? frank2334, Celbridge, Co Kildare Posted: 11/07/2017

This is greenflies and the empty skins when they moult look white.

The harm is not significant and they will go away.

But if you wish, apply a garden insecticide.

Something is devouring my Pieris, see photo. Is it the dreaded vine wievel, and if so, how can I get rid of them? Inish, Fanad, Co Donegal Posted: 30/06/2017

It does not look like the classic U-shaped feeding of vine weevils, more like snails or caterpillars. Keep under observation for any fresh damage.

Check it closely for greenfly and treat it if necessary.

  Leaf damage on Virginia Creeper
 

Leaf damage on Virginia Creeper

I planted a Yellow Wall Virginia Creeper early this year. It has been feed with blood, fish & bone, mulched and watered as required. About 6 weeks ago it was attacked by caterpillars (I think) so I sprayed it twice with an insecticide. Now the leaves have become paper-like and some have brown patches and the underneath side has white patches. Please see photo. I would be grateful for your advice. Inish, Fanad, Co Donegal Posted: 09/06/2017

Brown patches might be spray damage to young leaves.

White coating is mildew, which it will probably grow out of but you might wish to spray with Roseclear if it is severe. Spray in the evening of a dull day. 

  A 'sick' Red Robin tree
 

A 'sick' Red Robin tree

Our large Red Robin is sick. It's in a dark damp corner beside the shed, but was thriving up to about 2 years ago. The leaves are sparse, limp and dark, but no spots. There's another tree/shrub (wild & unknown) nearby but not that close. I planted the Red Robin about 12 years ago, shortly after we moved in. I was going to 'cull' it, but would like to try and save it now, as one of the 30-40% of stuff I planted that actually worked! Photo included. Ultan, Clonee, Co Dublin Posted: 07/06/2017

It looks like it has died of a root rot disease, especially if the soil  is heavy.

  Pest/insect covering tree
 

Pest/insect covering tree

Hi, A tree (elderberry) in our garden is covered in an insect. It a old/mature tree and all the new growth has insects covering the stems of the leaves (see photos attached). Some of the older leaves are covered in small flies. Is this harmful to the tree and what action should we take? I am a complete garden novice. ClaireLarkfield, , Co Dublin Posted: 28/05/2017

It is an attack by greenfly. Predators and parasites are likely to arrive and attack the greenflies. The tree is vigorous enough to withstand the attack and will recover, even if it might look a bit shabby.
