My flowering quince has lost most all of its leaves and has hard dark brown dried pods attacked to the branches. These trees are approximately 15 years old and have always been healthy and beautiful. They are fairly easy to pick off..but so many of them. The tree is planted next to a crap apple tree that doesn’t appear to be affected. There are no junipers or cedars in the area. How do I treat this and what is it? I spray both trees about once a month with malathion, as have had web worms in the past. None present this year. Can you advise me?
I sure can! this seems to be a fungal infection. My personal remedy is as follows: First, you will want to prime the ground with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil.
