Grisilinia with brown patchy leaves

  This grisilinia was planted about 4 years ago. Never had any problems with it before, but now leaves have brown patches - as per photo. 

There’s been loads of rain recently, as well as lots of very hot days. I removed a few leaves with similar damage a few weeks ago, but now it’s back and more extensive. 

Is this phytophthora? If it is, what can I do? Is there any treatment you can recommend? If it isn’t, what is it? And what can I do to fix it? I’m hoping not to lose the plant. 

Thanks in advance for any help!

p.s. not sure if relevant, but my garden is heavy clay soil (although I’ve done a fair bit to try and improve it.)

    P.s. I had never heard of phytophthora before today. It’s what came up when I googled it. I am hoping it’s not, as it doesn’t sound good at all…

    Most likely burn from the heat of the sun. Griselina leaves can be sensitives to extremes, and as mentioned, they have been subjected to excessive heat of the sun, followed by wet weather. Phytophthora usually causes the leaves to grow weakly and pale, followed by leaf drop.

    Oh thank you! That’s a much more promising diagnosis! 😁

    We're on clay too. Mine had the same problem a couple of years ago and, without consulting/googling etc, I just snipped off the affected leaves. Worked a treat and I didn't waste time on worrying. (Mind you I am a 'let's just try this' gardener).

    I put in place a “don’t google the symptoms” rule for my own health a few years ago - maybe I should do the same thing for my plants! 😂

     :D 
    I'd agree with @Borderline. They can be a bit susceptible to extremes of weather, and lots of shrubs [in particular] have had damage due to that this year. 
    I'm sure it'll be fine.  :)
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...
