Hello. Help needed please with my photina.

Hello
I’m new to this forum and hope to be an active member.
I’m in need of a little help with my hedge. Photina Red ribbon. My pride and joy.
The Attached photos somehow my problem, they are shriveling up and look burnt.
the hedge is in a big open garden and looks all elevations and gets sun 3/4 of the day ones side and 1/2 the other.
The hedge was planted 2 years ago and I’ve never had a problem. Every year around  April I throw some organic compost under the hedge and re lay a new soaker hose on top. Waters the hedge for 60minutes twice a week. Then I water as well
if it looks dry. When I do the grass.
around a week ago it started dropping its leaves and now it looks all burnt. I’m at a loss. I’m gutted because I’ve spent so much time making it look beatutfull and all seems to be going to hell.
can anyone help me diagnose my problem? It has also rained here in the Uk nearly lone stop for two weeks.

    "I water as well if it looks dry. When I do the grass." - I would test the soil of an established photinia with a finger to see if it feels dry. That will rule out lack of water but not late frost damage.


    "Waters the hedge for 60minutes" - I would try to determine if this is too much. The root system is kid of shallow so I do not know if the soaker hose is delivering too much water in 60 minutes. If I get enough rain here, I skip watering that week.

    It looks like frost damage to me.
    The leaves are burned at the tips and some mid-leaf, but not at the base of the leaves so it was probably nipped by frost just as the fresh delicate new leaves were about to unfurl so just the tips and sides got burned

    Pete could all the rain we have been having for last two weeks and then sunshine burn the leaves? The weather has been mad in the Uk for weeks

    I doubt it was the rain followed by sunshine.
    I've got very similar damage to my myrtle shrub. Last year it was covered in lush dark green leaves with a galaxy of starry flowers - it's looking a bit sad for itself now with burnt branch ends and brown crispy bits on many leaves. But it'll recover.

    Although I don't have any photinias it doesn't look like a disease or infection to me. But that doesn't mean to say I'm right either :)

    It does appear to have photinia black spot, but that's something many of them have. There is no treatment - it's not fatal, just a bit unsightly.

    Thank you pete
    it can’t be my compost can it? I have just as last year over laid compost as the ground had sank in places and having a shallow root system I didn’t want them exposing. So it’s all nice and level. I’m just thinking if the compost has somehow over fertilized them?
    would over fertilizing them cause this type of damage?

    What sort of compost was it?
    It sounds like you're treating them really well.

    It's not a shrub I have experience of although almost every gaden round here seems to have one (except mine)
    The only other thing I can think of is also related to the weather- see the penultimate paragraph

    It was the normal ton bag of organic compost. I believe it’s mushroom waste, but that’s just a quess as it’s stinks
  • Pete.8Pete.8 Posts: 11,340
    Ah!
    If it had an ammonia sort of smell then it may be a bit too fresh as mushroom compost is usually mixed with poultry manure which could end up burning the roots as the urea content hasn't yet been broken down by being composted for long enough. Sometimes the bags will feel a bit warm too if it's not properly composted.
    It also tends to make the soil slightly more alkaline for a while which may also have had an effect

  • Ah ok.
    yes when we had it delivered and started shoveling it it was red hot and was steaming. Looked like normal black compost though.
    what should I do? Leave it or remove it all?
    Thanks for your help on this I appreciate it. I thought I was doing a good thing but never realised I could hurt my hedge by that.

    I don't know what the consequences would be of leaving it there, but I guess there's less risk if it wasn't there, or at least if it was moved away from the direct root area until it's broken down a bit.

    I don't know if you could soak it out so that the concentration in the soil is much weaker. If the soil isn't likely to get waterlogged it may be an idea.

    Ideally a bit of both
