Q.Multi Grafted Apple Tree – disease?
We have a small 3 year old apple tree we purchased from a nursery. Last year it produced maybe 3 apples total, which more than we were expecting. This year we have many more on various branch types. However, some of the leaves are turning colors and/or getting spots and dying. Can you please help me figure out what is wrong and what I can do to help it? I’ve only been gardening a couple of years and I don’t know a lot about these things. I would love to have this tree for years to come. Please help.
The types of grafted branches are: Melrose, Yellow Delicious, Honeycrisp, and Gravenstein. All are semi-dwarf and we live in Oregon if that makes a difference.
Thank you for your time. -Kara
