    All you have to do is put some soap and water on this bush with a spray bottle and rinse off later and it will be all gone.

    Photos are very dark.

    It looks like sooty mold from the honeydew of aphids. Seen this on citrus.

    Post bright photos, so we can get a better look. :)

    Or it could Mites. But in either case it looks like insect damage. A pictures isn't always the same as looking at the plant in Person.

    hawthornes get this a lot. It seems to be two insects, leaf miner and mites.
    Merit drench. Also they like to get fungicide often mine look best when I treat quarterly with merit with a systemic fungicide or merit then second application of a contact fungicide

    I Bad, I left out Leaf Miner in my post and you can clearly see the trails in the Leaf. Hard Scale is another thing I see on Hawthorns more than any other Insect.
