Medium_image Lots of leaves on this Viburnum Emerald Lustre are discolouring and dropping.

The newer, outer leaves are fine. Problem is on the older leaves closer to the main trunk. It starts as small black dimples or pits on the upper surface of the leaf which cannot be scraped off.

Confidor tablets were put in at the start of July to deal with aphids. Weather has been cold and dry.

What can I do to save the rest of the leaves?

Answer: Hi Fiona,

Thank you for contacting Yates.

Yellow leaves could be a sign of lack of nutrients. Feeding the tree with Yates Dynamic Lifter Organic Lawn Food every 6-8 weeks would help the tree recover. You can see a picture of the product using the below link.
