      Thank you, Harry! We thought that creating a video on Quince trees in November was going to be a bit off-season, but of course for folks in Australia, it's probably just the right time!

    Hi,
    First, I would like to express my deep appreciation for your videos and educational content. I was wondering if you have an Instagram or email where I can send pictures of the leaves of the two small quince trees I purchased two months ago. They seem to be suffering from some problems and need urgent diagnosis. I keep them indoors in very large pots, and they are two years old. I have tried fertilizer, two different fungicides (copper-based and fatty acid-based), and have read many pages online. To provide different environments, I moved one of the pots to the outdoor yard one month ago, but even that one got worse. Could you please let me know how I can send pictures of these two lovely little trees so that this might be the last chance to save them?
    Thank you very much, and I look forward to hearing from you.

      Hello Aryaz,
      I’m sorry I’m not able to provide advice via email right now, but if you’re able to take a video and post it on your own channel then do let me know by commenting back here on this video, and I’d be happy to take a look.
      In the meantime, it sounds like your quince trees have been living indoors in their pots for a while and I suspect this may be the root of the problem. It’s very hard to have sufficient light levels indoors for trees like quince to thrive. Plants indoors are also more susceptible to pests like spider mites and thrips which can cause mottled leaves, yellowing and poor growth.
      I’m not sure where you’re based, but if you are able to take a sample or photograph to a garden centre then they often have staff who can provide advice. If you’re in the US then try to find a local extension service master gardener as they are great at providing advice.
      I hope you can find the solution! 🌸

      @@rebekahtheukplantdoctor Hello,
      Thank you for your prompt and helpful response. I appreciate your advice and understand your limitations regarding email. I do not have any TH-cam channel, so I have uploaded the pictures from one of the two little quince trees to a Dropbox link for you to review:
      Dropbox Link Click
      Please kindly note that I have labeled four pictures as "BACK of leaf" as the front and back of the leaves have different features. The back of the leaves contains very tiny dark dots that are not visible when looking at the front side of the same leaves.
      To provide some context, I am based in Windsor, Ontario, Canada. Unfortunately, quince is considered an exotic fruit in North America, and local gardeners are often unfamiliar with it. This makes finding knowledgeable advice a bit challenging.
      As a professor and scientist in medical imaging, I admit that I am not very familiar with horticulture. This is my first time trying to care for any plants, and I purchased them just two months ago.
      Thank you again for your assistance. I look forward to any insights you may have.
      Best regards,
      Ary

      I’m sorry TH-cam deletes external links so that’s not working for me.
      I think I’m going to struggle to diagnose without the images.
      However, if you’ve only had the plants two months then they’re probably still adjusting to being potted up. Plants often look a bit sad as they are establishing. Quince (Cydonia) trees should grow ok outdoors in Canada, so I think moving them outside is the best step. Check that the pots are freely draining and water thoroughly once or twice a week through the summer, rather than more frequent small amounts of water. You may find that they drop a few leaves as they adjust but hopefully new leaves will look healthier.
      If you have a Reddit account then you could try posting your pics in the plantclinic sub, see what advice people give there.
      Good luck 👍🌸

    Are fire blight and leaf blight same disease ??????????

      @@raajgan2895 hello Raaj, fireblight and leaf blight are not the same disease. Fireblight is caused by the bacterium Erwinia amylovora and leads to browning and die-back of whole shoot tips. In the case of quince trees, the leaf blight is caused by a fungus (Diplocarpon mespili) and leads to brown spots and blotches on individual leaves, and leaf drop. Hope that helps! 🌸

    I've noticed Quince Leaf Blight on a number of quince trees this summer (2023). You can easily spot the blight even from a distance, when you see premature leaf fall. Hope my video helps you grow in-quincable quinces! 😁🌷

    What about fungicides?

    • @rebekahtheukplantdoctor
      @rebekahtheukplantdoctor  6 หลายเดือนก่อน

      In the UK there are no fungicides available for use by home gardeners on fruit trees. However, if you employ a gardener with the correct professional spray certification (usually PA1 and PA6) then they have a wider choice of fungicides legally available for them to safely use. Spraying as soon as buds/leaves break in the spring is usually the most effective measure for fungicide control of quince leave blight.

      In the UK there aren’t any fungicides available for home gardeners to use on fruit trees. However if you have a spray license or employ a professional with a spray license then there are a few more options. The best option for control of quince leaf blight is to spray at bud break before the fungus has a chance to become a established 🌸

    Not helpful at all. I want to know how to treat my infected tree now, end of May not how to rake up infected leaves later. How to choose a resistant tree is irrelevant to my present problem.
    What fungicide can I use?
    Would bouillie bordelaise (copper sulphate and chalk) be effective?

    • @rebekahtheukplantdoctor
      @rebekahtheukplantdoctor  5 หลายเดือนก่อน

      I’m sorry you found the video unhelpful, gardening is a year to year process and often the best control measures are season dependent.
      Bordeaux mixture was widely used in the past for the control of a range of different bacterial and fungal diseases. However, copper based fungicides were found to be harmful to soil microbes and earthworms and hence they were withdrawn for almost all uses across the EU and UK. This has created a gap in the market and there are now no fungicides I can legally recommend gardeners use on their fruit trees. You will need to check with a local professional to confirm which plant protection products are available in your locality. 🌸
