The leaves of my Skimmia are covered in what looks like Black Soot, I have two which are grown in containers.

Please can you help.

Many thanks

Hi, Gerard,
Skimmia japonica 'Rubella' can get aphids. Aphids secrete a substance called honeydew. Honeydew encourages the growth of black sooty mould. Best thing to do is get rid of the aphids. Clean off the leaves first. Then spray with an insecticidal soap (an organic way to get rid of aphids) you can buy at any garden centre or use a homemade solution of water, washing up liquid and a little crushed garlic. You'll have to spray about once a week or so for about a month.
