Frequency of foliar feeding

I have some sick Cherry Laurels that I'm trying to nurse back to strength. On the advice of people here, I bought some seaweed-based plant fertiliser and have already done a foliar feed. However, I'm wondering how regularly this should be done?

Any advice would be much appreciated

Cheers

James

    Didn't the feed just run off the leaves? 
    If it did, then use the seaweed as a soil drench instead.
    Once a month-ish during the growing season either via the soil, or foliar spray if it does coat the leaves properly - foliar feeding is easier if the leaves aren't glossy.

    If you post a pic someone here may be able to identify the problem with your laurels.

    The feed stayed on the leaves fine. Used a pressure sprayer, and it seemed to stick it
  • this was my original post, where I got the advice to try a foliar feed - https://forum.gardenersworld.com/discussion/1025728/plant-identification/p1?new=1

    Since then, I've learned that my soil has a relatively high alkaline content (around ph 7), and is very clay'ey

    That sounds good then, a foliar spray about once a month on a cloudy day should help if it's a deficiency that's causing the problem

    Yikes!! just seen the photo.
    I think it'll take more than a drop of seaweed extract to sort them out.
    Maybe a severe lack of water, or something that shouldn't be in the soil

    You can check the likely type of soil in your postcode using this DEFRA related site.

    As others have said on your previous thread there seems to be something very wrong. Possibly something dumped in the soil or something leaked into the soil in that area. Are there plants thriving close by?

  • Hey Pete, thanks for the reply.

    I live in Scotland so the data on that website isn't applicable to me.

    Yeah, there's a few in a neighbours garden that seem to be doing quite well. I've attached some additional photos. Strangely it seems that the plants in the row that touches our house are far more yellow than the row that runs parallel to our house (which are relatively green). Not sure why this is?!

    They don't look quite so bad in the new pics.
    The best plan to try and nurse them back to health is to just make sure the ground where they are doesn't dry out, try and keep them watered.
    I wouldn't feed anything until there are signs of recovery, just keep them watered. 
    Were they firmed-in when first planted? This ensures the roots are in good contact with the soil and there are no air pockets preventing water getting to the roots.

    I believe that soil in Scotland is often acidic and cherry laurel is best suited to neutral/slightly alkaline soils, so if your soil has a low pH that's probably not helping.

  • Thanks for the advice!

    I took a soil reading the other day, and the pH is around 7, so quite alkaline.

    A pH of 7 is fine - that's exactly neutral, neither acid not alkaline.
    Will keep my fingers x'ed for you

    Dammit, yes pH 7 is neutral. Need more coffee this morning obviously!

    Thanks for all your help
