Milky coating on Hebe bush?


My Hebe bush has developed this milky coating on its leaves this summer. I wasn't sure what it was. But as it wiped off, I let it be. Now it seems to be spreading to the new growth, and it's sheading allot more leaves than normal. 

Is this something like box blight? Not sure what to do with it. Any help or advice would be appreciated, thanks.

    Looks like powder Mildew, its a fungal disease.

    Yes, powdery mildew.  Plants under stress are most susceptible and there is a lot of it about this year due to the long, hot, dry period.  Try giving it a lot of water over the next few weeks and perhaps feed the soil under it with something like fish, blood & bone.

  • Thank you for the identification and advice, I really appreciate it. I have done a little reading, and this does sound like it. 

    I will give it a good feed and cut it hard back.

    Check the variety before cutting back hard Gerard as some hebes don't like that and may not come back.

    I am not sure of the variety, but this has overgrown it home, and has been trimed back each year, so hopefully will regrow. I will leave the trimming until spring, to give it s good chance.

    Good, if it has responded to pruning before, it sounds like it should be OK.
