  • Leaf damage - celery and courgettes

    Hello

    I've got a problem with 2 plants in totally different parts of the garden.

    1) My celery was thriving then suddenly all the leaves starting turning white like tissue paper with black spots on them. Is this a mining fly?? I've removed all the leaves and disposed of them but even some of the new ones coming through look damaged. To make it worse, I found 2 similar looking leaves on my rocket - which isn't near the celery.

    2) My 2 lovely courgette plants which were doing really well, have suddenly decided to go on strike. They're both in grow bag in a sunny warm spot. The plants were thriving - lots of lovely dark green leaves and fruit. Now the leaves are starting to turn yellow (even some of the new ones coming through) and it's not producing that many new fruits/flowers. Some of the green leaves have a silvery look to them as well, but it's not powdery. I water daily as the soil gets very dry and feed with a liquid organic veg feed weekly. Am I overfeeding/underfeeding/overwatering/underwatering - is the plant dying??

    Sorry for all the daft questions, but any help/advice is greatly appreciated.

    Many thanks

    p.s - I'll try and upload some photos soon - my cameras not behaving currently

      Would be interesting to see if anyone has an answer to this as the same has happened to my celery as well.

        I googled, but haven't experienced this, but I think it may be late blight. Google Pycnidia.

          Thanks Taff. I tried a google search but didn't come across this site so really helpful

          Sadly I've had to cull my celery since posting this as it just didn't do very well and then bolted.

          I think I might leave the celery next year and wait until I've got more time and experience.

            Dolly, have you tried growing celery in pots and keeping the saucer topped up with water. I'm trying this method; as I mainly use the celery for soups I can use it like cut and come again. I am doing this with 3 different types, in the greenhouse, in a gravel tray that has an inch of water in it at all times and it seems to be working. It was suggested to me by a fellow Grape.

            This way you can also have it all winter. I only sowed another batch last week.

              Hi Zazzen.

              The celery I had was in a large planter/pot, but I didn't have a tray under it. Your idea of the gravel tray sounds great.

              I do eat a lot of celery and use it in cooking so would like to grow more.

              I don't have any more seeds this year so perhaps next year. Thanks for the advice.
